I could have sworn that I had already left a comment! I guess I just forgot!

Anyway, the art and sound effects were nice and clean, and the concept is cool.

I had a hard time reading the instructions because of the font, but it is interesting. Maybe adding a dark background behind it would make it easier to read. Also, I felt like the spikes on the first puzzle moved a little too fast. Also, checkpoints would be welcome.

Good job overall!
