I think the game is the right level of challenge for sure. I think maybe the mask guy just got stuck somewhere? I noticed there were certain tiles he wouldn't pass through. Idk how you coded him, if it was a set pattern or just "follow player" but maybe there was a collision blocking him or maybe it was a 1/100000 code bug that can't be fixed. Either way, I just rebooted the game so I could beat it while he was there xD
