Really cool idea! I think this game would be most fun when you are moving fast quickly dodging and reacting to the notes, but like others have pointed out, this is hard due to the camera. I also think that the gameplay feels almost separate from the theming? It really felt like this was going to have to do something with rhythm going in, and honestly, I think incorporating rhythm elements would really improve the feel of the game and add a ton of depth. Overall, great work, especially on that doodle style!
