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.

I still am playing my heart out in 42 but I've found a bug and it's something weird. Basically everytime i see an art screen (tif stealing sold) I can't chat after this I've found a temporary solution and it's closing the game and rejoining the match however, this makes roles like helper, maf, fana and cl very hard to play. Still love the game and will most likely never stop playing, please though if you can look into this so it won't happen to new players, -greenboi

I think we need a better tutorial when we first begin. I feel like it was confusing when you try to navigate the app after the tutorial. At first when you first start the game, it's honestly scary! But you eventually will get the hang of it. Mostly, your experience in the game is with the people you play with. Other than that, it's a 10/10 game. The art is amazing, and the timing is well done.
