Everything’s great but ONE

Could you please optimize the game to make it compatible with any controllers? Everything works fine until I connect my PS5 controller

Good game, but a lot of bugs.

This game is really nice and I got it not that long ago, but the problem I’m having that’s real annoying is logging out. Idk if this happened to other players but the game logs me out after about 5 minutes and I can’t even hardly enjoy the game because of it. So please fix this. I want to enjoy the game. It’s also very laggy too, but idk if that’s because I play on iPad. I don’t want to delete the game then redownload it because something similar like this happened to another on of my games and deleting the game and getting again made me getting kicked out of the game worse. So I'm not sure what else to do. But please, please fix this!. I really want to enjoy this game.

Управление

iPhone 14 Pro Max. Управление персонажем полный шлак. Не смог забраться на 2й этаж двойными прыжками. Кнопка прыжка, как будто в блокировку уходит. Ставлю кол за такое

Horrible mobile controls, clunky and unresponsive

Title says it all. It such a major headache to even try and play this game on a mobile device.

Great potential but some obstacles

Character designs are really nice, but the controls on mobile are horrible. They lack the convenience of other similar genre games. It's difficult to move forward in a straight line or to turn the screen while moving.
