Nice job! I played to the finish (plus bonus rounds, of course). Really smooth player movement and glide -- the game has a really nice feel in terms of the gameplay. The artwork made great use of the b/w, the UI mechanics all work well, and the menus and sound effects gave it a nice polish.
I enjoyed the gliding so much that on Bonus level 9, I glided right over the little white collider that ends the round (I figured out its function after a few plays) and into the abyss, and needed to restart :) -- the only such thing I found.
Nice work!
