Really love this game and have been speedrunning it lately. I was wondering if you're still working on any patches/updates because I seem to have a somewhat repeated crash/bug. Each time it starts with the audio repeating the same half dozen notes and then the game crashed out when either trying to save or when losing the final heart and returning to the last campfire.
If it helps, you can see it twice in this vid
Happens around ~20:51 and around 27:08.
