Good job! Like others have said I really like the artwork! 

I may have found a glitch while playing. I ended up touching a small (blue) building when I fell past a ledge. I was further away from the building than normal and pressing the spacebar wouldn't fill the bar. I'm not sure how this works behind the scenes, but I'd imagine I fell out of the building's hit box but the player object couldn't leave "power mode" until the building's bar was full.

Nice little game.  Here is my playthrough of it.  One of the maps had a bug in full screen mode.

Fun Game the Art was really good and I really liked the music. One thing is the game was scaled weird so I could only see the players hat.

The windowing was a bit strange, but I like the idea in this game! Nice job!
