Answer 1

good first level. for the future, make sure that your checkpoints spawn you on the floor

Answer 2

Not bad for a first level!

I had some problems distinguishing layer 19 (collision layer) and background stuff. Also usually more dust != better. The last room for example is just a pain to clear, and a few occasions with walls, you had so much dust on it that you forced the player to slow down.

Answer 3

Cool first level! The last room did give me a bit of trouble, it wouldn't be so bad if the super cleared everything but it doesn't clear dust that isn't in line of sight of character. I also tried climbing to the top and ran into some trouble finishing the level.
