Very cute art. The spookiness mixed with cutinesss is a really nice combination in my opinion.
Liked the companion system, although I think it's random right now and on my first run I got nobody and on the second I got 2 witchies on 2nd and 3rd wave. I would look into implementing a system where you if you don't have any companion by the 3rd wave it's 100% chance of getting one, so people won't get screwed too much by bad RNG.
Realoding system could get some kind of feedback(either sound or some ui telling you how long until you reload). Not having any feedback on it made me really confused at start.
But really solid entry, I have to say.
