I thought the artwork was really nice and cute! You implemented a few different enemies, and interesting spells. So there was a nice bit of variety and fun!
A few pieces of feedback for your next game or if you decide to expand on this: definitely work on making the movement and dash feel a bit more natural. You can do this by adding some acceleration and deceleration. You can also add some feedback when the enemies get hit by spells. There were a few moments where I didn’t know if I was hitting the enemies or not. Finally, the white background was super bright and got a bit hard on my eyes. Maybe a light gray or a super light purple would have been better.
Great work!
