Thank you for the prompt reply and for actively trying to sort this out for us! I love the game so far and simply want it in the most polished state for all to enjoy.
I just tested the newest (FlashCart) version and it is doing the same thing as the others.
To assist in troubleshooting where I can. On my cart (EZflash) it is recreating the save file on every boot. I can collect the gems and complete a level but it never appears to be actually saving the progress as once I power cycle I can only pick new game again. Or it's simply just overwriting the save on each boot (thus appearing to never save)
Happy to assist where I can.
Cheers

Sorry to bump but just asking, are you using an Analogue Pocket? I had that issue that the Analogue doesn't save the gems at all, I could play the game, power off, reset, continue, power off, etc etc on a GBA or GBC and everything will be there but as soon as I take my cart with that save working and put it on the Analogue tobo play, as soon as it "saves" all my gems are gone, tested it multiple times and always happened the same, so if you are using the Analogue that's the problem, if not, well, there is something else going on that we need to find out.
