At the start of the jam my level generator wasn't working the way I expected, creating levels that just had individual wall blocks sprinkled in the arena. I felt it worked fine for the game so I didn't try to fix it due to the time investment needed to make what I had already done. While working on code to fill in disconnected holes, I found out that the levels weren't generating right due to a tiny off-by-one error when deciding whether to set tiles to wall or floor. The levels are now much more cave-like and as I originally intended.
