Thanks for the web version. Firstly - the music was pretty good! Very epic. I didn't quite get what the paint buckets did, I noticed I got a cape but didnt notice anything other than that. Also on level 2 I was able to complete it without the paint bucket by just running through the spikes and enemies whilst flashing. With a little more polish and perhaps a tutorial level to explain the features and mechanics this would be great. Good potential - well done!
PS - I didn't know I could double jump until my 3rd or 4th try :)
