Also happened to me, you simply play the game as a "gba" game by only using the dpad and buttons. Try pressing up on the dpad to select

I also got it, it's very probably because the game targets a lower SDK than required (game was released last year but Android reads this magic sdk number and if it wasn't properly set when compiling the app it thinks the app is waaay older and results in this error).

There is a hint, pay attention to the signs

Tried to install the demo on Android and it warned me about the app being unsafe because it was built for an older version of Android, maybe it needs to update the target SDK version to fix?

I would appreciate the Patreon build here as well for paying a certain amount in order to unlock the file.
