Yes, this is the package from itch of course.
Play Store APK has version 18(11) I think, while Itch package has something like 1.0.
And there's a bug in the itch version when hitting Quit opens settings instead.
Hey! I uploaded a new APK version yesterday, hopefully fixing all bugs. "Quit" button is not very standard for mobile apps, so I removed it. Also removed the store for the itch.io version since everything is already unlocked. Everything should be working now! Thanks for the reads up about the issues :D
