This story is so fucking good. Least toxic most toxic yuri I've ever seen. Made me feel emotions I can describe but often don't want to. So glad I followed up on finally playing/reading after all this time of it sitting on my computer.

(+1)

My ex is named Ember- I helped her pick it- WE WEREN'T THIS TOXIC THO (also was not WLW)

I was entranced the entire time, this was INCREDIBLE.

(+2)

Holy fuck. That is so unhealthy, but it could be me after coming out, if I get unlucky enough.

What can I say, it’s peak I guess

It was crazy good!!!

To think I would find my fetish out in the wild, Im so lucky...! And the storytelling. And everything.  Im delighted, thank you.

Absolutely incredible. I didn't expect to resonate quite so much with Ember but sadly I do! The art was beautiful and the music set the scenes so well. Just a really great VN overall.

So fucking good. If this was on Steam, I'd give a full spoiler'y review for it, but, in lieu of that, 10/10 absolute peak.

god what a freaky game, ill be honest it was anything but what i was looking for but i think its what i needed. great game. 

really really cute!! read this after finishing passenger princess last night and its really cool to see your thumbprint and style. i really love the music and the visuals! you have a really good sense of creating atmosphere and a Vibe through it all

(+4)

i really liked it! such a horror story..

Mill's opinion on being a vampire felt quite new to me. a creature not tormented by guilt of the needed cruelty, but by mundanity of it?? for some reason i've never heard this take on vampies before, its interesting thing to ponder...

got scared that after ember leaves mill for the first time that was it (even though it would mean some kind of a good ending for her..), glad there was a little more. the first part of the story really lets you into the depths of their sad minds - and to know that this isn't the first time ember's been treated this badly and its Just Another situation in this neverending nightmare :(

as a non eng speaker i can only imagine how constant switching between 'her' and 'it' in regards to ember just minimizes her to a mere thing..

in my mind in the end scene mill turns ember into a vampire (making her Hers) and the cycle of weird stuff continues..  maybe ember finds some kind of autonomy by new awoken needs and new powers? but it still will be a story about broken girls 

and artstyle really adds to the atmosphere! cant wait for more things from you if youre planning something.

(+2)

SO FUCKING GOOD  AND LIKE  WHEN EMBER  GETS THAT UNHINGED LOOK IM LIKE YEAHHHHH SHE GETS IT

(+2)

what a wonderful game, short sweet and soul wrenching all the way through. 

(+1)

Excellent job. I think the hallmark of a good game, and most things involved with storytelling, is when it makes you feel something. There's something cathartic about the doll's perspective as, myself, a survivor of trauma, and I could feel her relief in her surrender. It got me a little emotional. The art is stunning, the music is very fitting, everything comes together very well. This is a little gem. Thank you for bringing it to life. :)

the art is really hot

what. the actal, FUCK... THIS MAKES ME PLAY PRETEND PICASSO WITH MY BRAINS

(+5)

"i can fix her" says girl who wants to kill and eat her lol

(+2)

First I've read of yours but really well done. As others have said I really enjoyed the composition, feels like a very competently done vn, good length too. Art is fantastic always, a little jarring, a little unsettling, but thoroughly  enrapturing.

The story is a hell of thing. The thing that really solidifies how well you've accomplished your goal of toxic yuri is basically from the first moment Mill and Ember meet, you can tell there is something more than just a prey-predator relationship. Especially Mill, she's in love before she even knows it yet. A fascinating, grotesque, scary, honest love. I'm not really a toxic yuri girl but I follow your twitter bc you really do post some fantastic art and there is something very powerful in the thesis of your art and this vn which draws me in. A vulnerability, a rawness that I admire. It's emotionally stirring. I congratulate you.

(+2)

doll is so relatable lmaoo idk how im still alive

(+2)

While this VN was in development, I remember seeing one of the CGs for it posted online; I believe it was the one with Millificent and Ember spooning in bed?  And when I saw it, someone had left a comment on it to the effect of, "This is how it felt to hook up in the psych ward."

I have to say, having read the full story now, that description feels as apt as ever, heheheh~

I could tell you had quite a lot of fun making this one, Harley, and I loved to see it~  I also loved to see all of your art: As ever, it was all very distinctive, highly expressive, and well-executed on a technical level.  In fact, the technical execution, visual presentation, and overall direction for the VN were on point from start to finish!

It was great fun watching the dynamic evolve between Milly and Ember, twisting from something openly predatory to a peculiar sort of affectionate "Making Her Worse" codependency, heheheh~  Hell, it's a small miracle in its own right that Ember managed to survive as long as she did to meet Milly, with how thoroughly and intensely prey-creature-coded she is; is it any wonder that the same thing happened to it at the same bar twice?  Perhaps it'd even happen a third time, were Ember left to its own devices there for long enough again...

But yes, great work as usual, Harley~

(+1)

Ehhehhee thank you Kyou.... I also still think about that comment, that's more or less what i was going for. Glad you enjoyed...

(+1)

Really adored, as much as the last work I read by you. The art is fantastic. Your compositional work is always impressive. Millificent is perfect, and I really enjoyed Ember too. Millificent is the kind of girl I find myself thinking about often (and Ember too really but in a different way).

The layout / gui changes are really god too. I enjoy the smaller icons aas it keeps me focused on the words . Not that i couldn't help but stare at Ember or anything haha!

Excited to see everything else you make! 

WahHHhhhh thank you so much Mala ;_;
Happy you enjoy both characters, I think a lot about Millicent and that type of entity too so I'm glad... Everyone stares at Ember anywhere she goes so it's ok, that makes it fine... Mill will protect her now....

Thank you so much for your lovely fanart also, was really excited to see it, your art is wonderful. Really liked Meat Girl, I need to get around to playing your other games ksdfghkdfskhg. Tysm ^^

(+1)

gorgeous and also really painful, which the best thing to pair with gorgeous <3

(+1)

Thank you..... a little bit of pain is important... like eating your veggies

Reading this was an absolute trip, the twisted chemistry between Millicent and Ember is just utterly intoxicating to read and I was not ready for the story to be over; I need more of these two. Right from the moment Millicent appeared in the bar I was hooked, you have such an incredibly visceral writing style that makes everything hit so hard. All that and an utterly breathtaking artstyle definitely makes this one of my new favourite visual novels, I adored every minute of this. 

(+1)

Ehehhehe thank you very kindly. I'm happy it came together for you.

(+3)

my autistic ass is hyper fixated on toxic yuri for the thousandth time and i stumbled across this game and its so good. props to everyone that worked on this vn, i am so very different from ember and Millicent but i cant understand how they think. 10/10 vn will look at the rest of the content this author has posted. have a wonderful day/night

(+1)

I wrote this in the review, but I also want for the comment to be left here, too

holy peak, oh my fucking god

Even though I lead a much more(-ish) comfortable life - physically/materially - than Ember ever did, I can relate to both main characters, as within them, and as outwards of them. How they feel on the inside and what they express on the outside. also inward desires/outward desires? I don't fucking know

the beginning part where Millicent tried to care for Ember reminded me of a quote/saying that goes something like "you cannot make someone love you by loving them harder"!

also "live-in-girlfriend-dog" was kinda funny and the more technical/meta parts with uppercase names/name colors changing were pretty damn good too. It tells the story in a way only the inclusion of elements like these can.

sorry I can't fucking do analysis I can only voice my thoughts and feelings

I will be coming back to this later in life.

Thank you kindly, happy it hit for you

(+2)

Talk about hitting you where it hurts. damn. maybe Ember is a bit too relatable....

Mill's dialogue is also perfect. crazy to admit to white text on a screen from an vn character flustering me so hard but, gosh. You did some amazing work here, I hope you know that! <3

Much appreciated..... I'm glad people enjoy Mill hehe

(+1)

Absolutely fire dynamic. Love the art, all the music used, and you have a hell of a way with words. Good shit.

Thank you, glad to hear it ^^

(+2)

AAAH another of your vns, i'm so happy to be playing it. forever love your art

ember living my masochistic dreams UGH i get her i'd also willingly submit myself to Mill. to spiral and get worse with someone, encouraging the darkest desire that lives inside, the yearning im feelinggg. 

this was so gooood i need more of themm

wahhhhhh thank you so much lilly.... i'm glad you liked mill. me too.

(+5)

holy fucking yeah, this has peak vibes

from the opening of ember "being between names", I felt so fucking connected to her. ember is a peak display of self-immolating & preservation-lacking girltype that I fuck with so hard, and find myself being from time to time. 

The density of CGs on display here is truly impressive too, as is the sheer act of making it all work in RPGMaker with this level of fluidity and polish!

I am so normal about the phrase *live-in-girlfriend-dog*

The violence that you wrote here is fucking intoxicating, and hits all the right beats of mutually spiraling and egging each other on. God I love Ember so much ghsdfhdg

Thank you so much Snek, I consider that high praise coming from you haha. I'm happy it hit for you ^^

(+3)

I downloaded this game and started playing it worried it might be gone if I didn't grab it now with everything going on and 

gosh

I feel very seen by this. I was kind of disappointed it was so short, actually; aspects of Ember, her disdain for her past self, how touch starved she is, her difficulty to speak what she wants, how she's been sort of made to be someone subservient to others and comes to realize she genuinely wants to be Mill's plaything/prey...Its embarrassingly relatable >.<

I started this title in particular because beyond being a fan of yuri and darker subjects I wanted to read something that made me jealous of one of the characters. The s/m angle of it was really hot and left me wanting to be in Ember's place at Mill's mercy myself. 

That said, beyond just the general "this is hot" I really appreciated the thoughtfulness and understanding of what trauma does to people, how it changes someone in ways that are really hard to escape and break out of, and even changes what people want. I also appreciate the inclusivity of it; Mill may be a vampiric predator, but gosh darn it she isn't a bigot. The writing was very good and I was constantly left wanting more. 

Thank you kindly.

(+2)

Finally had time to play it, I forgot it was for toxic yuri but the story was as intoxicating as they were for each other. Really loved it, when the power between predator and prey continiously shift while the role stay the same, it's always make interesting events. Really make me want to draw fanart of them now ^^'.

thank you, glad you enjoyed the dynamic.

(+2)

Love the game and writing, yes i'm the sameguy with the shity pc from newgrounds i dont think i will write a new review, only writing this for engagement

glad to hear you were able to play in the end. thanks for checking it out.

(+2)

I found your stuff on a list of delisted / removed adult games on itch and was wondering if you were up to me listing your stuff on my site. I also would be down to make a page for any free games / demos that got straight up removed. I’m trying to reach out to people and help out how I can.

thanks for reaching out. i've got my own plans for hosting things but i really appreciate the offer.

(+3)

This was actually really wonderful to read... like, despite everything Ember's been through it feels really hopeful. The scene where her and Millicent are just sleeping and cuddling in bed was so cute... it sounds strange to say because of everything that happened through the story, but this made me really happy to read. <3

I also wanna add that your art is amazing, and that the music was really REALLY good!

(+1)

thank you... really appreciate the kind words

(+2)

ahh, this one has been more relatable than i'd like to admit, and has been hard to read at times (thanks for the CW). but I'm glad I did, it's beautiful often in fucked up weird ways. thank you.

thank you, glad you enjoyed it despite having difficulty. important for there to be fucked up weird girls living their lives.

(+3)

Symbiosis! Yes!! The interplay between the sadist and masochist! You got to the beautiful heart of the matter with targeted intensity. I loved this so much. I will be holding my breath for more from you! Thank you!

thank u so much... i will endeavor to continue making games with this level of intensity

(+2)

This was a really intense read. I kept feeling taken aback by how much damage Ember was willing to take, and how much she wanted to take it

thank you, glad it felt impactful.

(+1)

omggg this was amazing i love your work so much ive been excited for girls symbiosis for a while now :333 ive never gone "shes just like me fr" so many times in a story before

thank you... glad you found it relateable

(+1)

Girl's Symbiosis boasts striking art and music, intense scenarios, and fascinating dynamics in its short playtime. If you like blood and are seeking some toxic girls entwining with one another outside of typically accepted norms, this is the one for you!

thank you so much....

(+1)

Your art is tremendously compelling as always, extremely expressive and emotional. you have a knack for honing in on the essence of a feeling and conveying it through your linework. the music was great, and the story was very enjoyable. Thank you for sharing.

thank you death.... happy some of those feelings came through... really glad you enjoyed it >.<
