- Nice art and a good variety of music.
- I would like to be able to jump with W. Perhaps you can also add controller support.
- It's great that there are checkpoints.
- Something is broken with signs; often don't like to appear when I press space. It's almost as if you have to look at a different sign, before you can active the sign again.
- The movement speed is very slow while you're on a moving platform.
- The area pictured below was too difficult for me (I think it's in the second level). The dark purple enemies are also too difficult, since their projectiles follow you around.
