The game appears to not work in this current version. It detects a save file from the 6.5.3 version, then the main menu shows "Nude Byte - Random Run" and no other buttons appear whatsoever. I've noticed it displays "your device is set to <lang>, not english. This may cause issues while playing the game". Previous versions correctly detected the language set (instead of <lang>), so I'm not sure if the game isn't working due to that reason or something else.
EDIT: I tried re-downloading and using a different folder in a different location, and now it works. I have no idea if it's anything you may wish to check out or not, since I also don't know what caused the game to not work in the first place.
