I rated this a while ago, but just now read the reviews after getting (I think!) every ending. First, I'm not sure which platforms this is available on, but I played on PS4 and you do not have to use your phone to control the game - you can just use the touch pad on a normal PS4 (dualshock) controller. My wifi can be really spotty in the bedroom and I can't get my phone to connect to the same connection that I have the PS4 on so this made me very happy. (Plus I'm not really a fan of games that force you to use your phone as a controller unless they're like.. Jackbox games.)
Next - the story is genuinely mysterious. As the game says on the first load screen, it's impossible to get all the answers with one playthrough. After playing multiple times, I can say with sincerity that you can have a COMPLETELY different experience from one playthrough to the next.
Oh and before I forget - if you're a trophy hunter, this is an easy grab. It'll take a couple playthroughs and certain parts can get a bit repetitive, but you'll go into certain choices armed with the knowledge of the last run, so it's necessary. Also, you don't get any trophies until you complete each playthrough as to not spoil certain plot points - so you must complete it in order to get them. It's easy to lose track of time when playing a video game, but I THINK an average playthrough is about an hour & 45 minutes. Sometimes longer, sometimes shorter.
And finally, it really feels like A LOT of work went into this. Not only is the story incredibly complex, but the gameplay, mechanics, pathways, and yes - even the controls feel like they were crafted with great care and detail. I'm not sure of the budget for this game - but it LOOKS like it was at least 7 figures. If not- then even more kudos to the devs.
I'm a fan. I really need to look into the streaming rights for this one.
