First of all. The art was Great! Really stunning! The music was great. It accompanied the gameplay really well. However, even though the game might have been tons of fun, I couldn't really play it because my keys were mapped to 'Q', 'S', 'D' and 'Z'. Which meant that it was super hard to move around. Another small issue is that the sound effects are super soft.
If you could fix these small issues, I'm sure your game will be great! :)
