Hi.
Since you compiled your game with Ren'Py v8.1.1, it no longer works on my tablet. Inded, this version of Ren'Py is not stable and does not work on certain devices. While I'm playing, the screen jumps at times, as if the game were trying to change the screen resolution. And after a few minutes, the game either displays a frozen black screen, or suddenly closes.
The problem is similar with all games compiled in Ren'Py 8.1.1 and only with Ren'Py 8.1.1. I'm on a Samsung tablet with Android 12 (native). I borrowed another tablet (also Samsung) to test, and the problem was identical. I've tried the PC version (via JoiPlay) and the Android version, and the problem is present in both cases.
Only solution: I borrowed a PC, decompiled the PC version of your game, then recompiled it with Ren'Py v8.0.3. With v8.0.3, your game works perfectly on my device. Unfortunately, I can't borrow a PC to decompile and recompile for each update.
Until Ren'Py releases a stable version on all devices, could you please use Ren'Py v8.0.3 to compile your game?
