Thanks for playing! I'll have to check out sprite masks for sure, I had an idea of the spirit world having destroyed/damaged walls and windows but I wasn't sure how to implement it best.
The enemies are relentless, I agree. At one point I was thinking of giving the player infinite life just so people could play through. I really messed up my enemy state machines honestly, it was so much spaghetti that I just couldn't fix anything :D
