Pretty rad!
I had lots of fun. Pretty damn addicting! While I do agree with the others that the music gets a tad repeatitive, they should maybe consider TURNING THE FUCKING MUSIC OFF instead of marking you down for it. And as for the game not being an actual "level editor" like the name implies, Doctor Djm is right. It's a play on words you twits. My only suggestion would be to be a little more creative with your character and setting. You see stickmen a lot here on Newgrounds, and I think your play mechanic was a missed opportunity for a character with a cool special ability.
Anyway, fun game! Kept me playing till level 20, and I'm definitely coming back to finish!
