Great game, I can tell you are inspired by Undertale! The art is amazing and the gameplay is really fun too. A couple things I would note, I didn't really notice that I get faster when I'm hit, maybe this could be made a little more prevalent. Also the attack variety was nice but it sometimes felt a little random. I think it would work a little better if the attacks more more telegraphed to give the player a better chance.
Overall, awesome game though. I had a lot of fun playing it!
