Nice entry. I like the music in the background, and the color scheme you used. The player character looks really awesome too. You did say this is an unfinished game, so I think that explains why there is no way to progress out of the first level (or I missed something, i collected 14 coins then fell to my death) or no enemies to use my cool attacks on. The retracting spikes were a pretty good idea. If I would give feedback, do add feedback for when the player gets hit. I couldn't tell when spikes hit me and when not. Anyway keep up the good work!
