Fun little puzzler. It took me a little while to realize that I could take my arrow back out of a demon. Also I noticed that you can press N to go to the next stage at any time, you don't actually have to solve the puzzle.
Thanks for the feedback! The arrow was a tough game design challenge for me, glad you eventually found out!Thanks for reporting the bug, I will fix post-jam. At least the ending is hidden behind finishing the actual levels :phew:
