that's great news about 1.2.2! Thanks for that, I'll have to grab it.
Originally there was a save function, but the built-in save function in GBstudio would save some variables but not others. We couldn't overcome the bug so we removed it entirely.
It's a shame, because it's quite a long game. Playing it on emulator means you can quicksave, and that is enjoyable.
Without the saves it made the game more punishing, so we made death less damaging. In this build it just resets you to the first campsite :~)
