File updated, please try again)
Thanks for waiting! I couldn't catch this bug on any of my devices, but it seems like there could be a problem in the game engine itself. There is a lot of information about similar behavior of renpy games on Android 11, especially on Samsung devices. So I have just recompiled the game with the updated renpy. Could you please remove previous version of the game, and check this new one? We will update it here if it will work for you.
