The error that persists now is the game will not save.

I understand; I don't have an EverDrive or an EzFlash Jr. to run the necessary tests myself. However, I'll investigate the issue with my team, and once we find a solution, we'll post an update and a reply in this thread to let you know. For now, I've uploaded a new version of the ROM under the name (For FlasCart), recompiled from scratch. Thank you for your report.
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
