Beautiful game with a great atmosphere. I actually played it 5-6 times to the end to see the effects and what happens if I get to 0 coins or health. It is a very well polished experience, which is impressive as a solo dev. The pacing felt a bit slow in the beginning, but I came to accept it after the third playthrough as part of the melancholic tone. The gameplay is very simple, but I think that's okay for a jam game.
One issue I found is that the Retry button didn't seem to work when I died after reaching 0 HP.
