I think having some type of tutorial in the game would be nice. At least to show what the goal is. Not many people are willing to put a HUGE time into game jams so adding a tutorial would be a good way to keep them from losing interest.
I was confused as to what I needed to do and didn't realize I needed to damage myself, but once I reached the next room I wasn't sure what to do and lost interest.
Cool idea nonetheless, just needs better execution
