Install instructions
Make sure to extract all files out of the zip before running.
Mac users might have to disable some code signing or verification thing? I'm not exactly sure, I'm not a mac guy. I'll get some specifics soon.
Linux users have to make the file executable, using "chmod +x linux.x86_64". You're running linux, you can probably figure it out.

Can You Censor Swear Words On This
aura

Code: GNYS
this is what it fells like to face a player that has ice flower..
Game crashes when i spectate and leave mid match :(
just fun, good fangame
comments are REALLY lagging lmao (oh hey i actually was able to comment something)
hello! if you can, could you maybe add a spectator lobby mode that lets spectators return to the lobby to chat? it only makes sense since match details show up in the chat after the game. i think it would be really cool to have the start button be a "spectate" button after the game has started.
ever since 2.0 released this game has been peak on top of peak
also how can I see my replays
this game is fun, but these sweats take everything tooo seriously and start crying lol

computer type: Chromebook
omg i havent touched this game in a HOT minute. i still really love to play this game outside of school
i really like this game! the only thing i don't like are the sweats that take everything seriously...
What if there was a mode where you had to win via eliminating other players by hitting them with the powerup abilities and the hazards in the levels, because i like it when you have to fight in order to win instead of having to collect and or keep a certain amount of collectables to win. I had an absolute blast playing with lives on in bricks with an astronomically high number of stars to lower the chance of anyone winning via stars so that the main way of winning was to eliminate the other team, very very good game btw keep up the good work!!! :D
om ma gaaaaaaaaaaaaa
It's my 2nd time that I'm banned from the game and this makes me furious! The last time I was banned was for slurs and this time for Inappropriate Names! ipodtouch0218, if you read this, please can you fix this for me? My nickname is always DoPikaBro2005 in the game and I apologize myself and you for these bad names! Can you please forgive me and make me unbanned? This is ridiculous! :'(
i wonder why you were banned.
I've received 2 bans in 1 year, but it's already expired. First I was banned for slurs and bad language, The 2nd time I was banned was for inappropriate names. But don't worry, My nickname will now stay be DoPikaBro2005 and just don't think about it. It's already gone, But this my last chance not to do that again or anything else that is bad. And if I do that anyway, I'll be banned from the game... FOREVER!!!!!
The game is really good, sadly, tryhards in this game are so annoying.
when i see Pepe El Mago playing this, i thinked that it will requier a ROM of the original game, but not
For some reason when i press play on the home menu it just beeps at me, and it's a unskippable pop-up. and can somebody help me through here?
how is this possible. so damn good
this is the best game ever.

Hey! I'm building a website that collects fun browser games and I'd love to feature yours. Would you be okay with me embedding it via an iframe? I'd include your name, a link back to your itch.io page, and full credit. No monetization on my end — just sharing games I think are cool. Let me know either way!
whats the website called? sounds interesting
it's a bot, I swear.
if it's a bot, then why would it say "no monetization on my end"?
i dunno
Love this me and my partner have enjoyed playing it
A recommendation for a feature would be a possible randomise room/level option.
ca envoie du lours de mod j’adore !
any plans on just making this p2p or an ability to self host in some way
Unfortunately it's not possible currently just because of how Photon Quantum (what the game is written in) works, requiring a central server which is proprietary.
😔
i made a video of a modded version called miibumm's mega item mod so i'll upload this video soon when i finish playing Pkmn rumble blast
hi :DDDDDD
