Good idea, but I have problems like always.
Hitting spikes does feel a bit too good, so I didn't realize how bad they were to touch. A negative feeling should be with negative things, but only a little bit of a negative feeling.Maybe a dissonant note for when you hit the spikes. Also, the graphics are blurry, but that might be only on the WebGL version. I couldn't know.
But overall, even though this is done in levels really badly, it works by itself. It is a good title if you are bored,and that's good!
Good job at this game jam!
