If you are on an Android tablet I would recommend trying the file labeled Gacha Redux Beta 2.apk first I tried other apk first and it didn't work but this one did for me EDIT: this is very nice good work on this mod
I'm on Android and every time I have tried to open the app it exits and says "Gacha star" Keeps stopping it might be my devices model that's the issue but if anyone else has this problem your not alone also all the other gacha mods I've gotten have worked without any bugs along this line
