Nice job! I especially love how the title screen is fully black until you move the mouse over it - that was a very nice piece of polish that I didn't expect. Gameplay wise the controls were responsive and easy to get the hang of. The guy floats in the air for a long time but I actually prefer that because it makes hitting some of the platforms a lot easier. My first play through I didn't even realize that there was a battery gauge so you might want to make that more visible so people know it's not unlimited.

Congrats on submitting!
