Oh, if you're using fake-08 then that is probably why there are issues with the saving data like highscores (it's also probably why "try again" just reboots the game instead of restarting the game mode you just finished). I'm not sure if I can fix it in my game as that may just be an issue with the fake08 emulator. If there is a way for you to run Pico8 natively on your Miyoo Mini Plus that would probably solve the issue, but if I find out another work around I'll let you know
