editing this review after 3 years. this is a great game and I've played it since like 2019. its incredibly fun and a great way to kill time. some negatives would be one, the tutorial. it's a very basic tutorial that really only shows how to use two roles when there's like over 20 roles on the game. it leaves the noobs struggling to learn to play which causes awkward fights in rooms. two, the role changes lately. they've been nerfing roles/perks that don't need it and it ruins gameplay

This app gets away less credit than it should. it's really fun, has plenty of characters, and has got me staying up nearly all night playing it. sure it can crash sometimes, but if you join the same channel it'll allow you to go right back in if the game hasn't ended. some people say that there's a ton of toxic players, but it doesn't happen often. this 100% deserves a five-star total rating, as it's one of the best games I've played, however it does randomly crash and I lose a turn, please fix.

This was a GREAT game before the newest content update. Lies could actually work, it was fast paced, everything felt somewhat balanced. And then it all changed. You could tell what roles there were in game, so lying was pretty much out of the question, the animations, while fun the first time, just took too damn long. And then, there's the back alley. Default sets couldn't win. It doesn't sound like it, but this was my biggest gripe. Nobody wants to play and that sucks cause it was great game.
