I really enjoyed the charm of the art style. And some of the effects were really cool. I thought it was a clever tie-in to the theme as well.
Some suggestions for improvement:
- Maybe it's just me but for the first couple of levels I didn't realize how much damage I was doing to myself with spells. Perhaps more clarity around when I'm taking damage would help.
- The night level was a little too dark. I couldn't see myself or enemies.
- It wasn't always easy to be precise with my spell casting direction. Maybe some subtle indication of that could help without being distracting.
- I may have missed it, but I wish there was some volume control because music / SFX were a bit loud for me.
Overall, I think it's a great entry and has a lot of cool stuff in a short amount of time. Great job!
