Honestly, that's a neat idea. That would be interesting to see! Also, that is indeed an unforseen bug. However I know exactly how to fix it. Thank you for letting me know!! p.s. Were you able to find the weapon upgrade? It's hidden
Wait also there was one more if you don't move once you enter the boss fight you will take damage from the spikes on the ceiling, and yes I did find the upgrade in level 2
