Love the game, will never run

I have tried and tried to get into the game off and on for the months it has been online. It is no where close to optimized for mobile and in my eyes if you are going to make a game available for mobile your mobile optimization should be the priority. You have such a severe data leak or what ever is going on that it is absolutely refusing to run the game on any graphical setting that is attempted. So basically, constant crashes even with the latest of funs and everything else shut off but the game. Suggestion is remove it for mobile in its entirety and fully lean into PC and make it a real video game instead of half assed, mobile is holding you back.

This

This game is genuinely so boring which is sad because of how pretty some of the designs are and if feels damn near impossible to get characters

Can’t even login

You give me the option to login with google on pc but don’t on mobile. Really?🫩

Give it another chance

The game does have problems but they are fixable and the Devs seem motivated. I gave the game a chance and I’m really enjoying myself.

Walking

I wish there was a way to remove the walking button.
