Things I liked: I like the idea of having their stats affected by the environment. I also enjoyed the music, as it wasn't just a typical synth beat with drums. The art itself is a great style and helped draw me in while I was playing.
Improvements: There is a bug where the options menu stays open if you do not physically close it. It's hard to play the game with it open. I also had a hard time understanding the effectiveness of my attacks. Adding some sort of health bar that can go up and down on the enemies, or even an audio clip that plays would make a great addition.
