Cute robot. I like the music and I like the level design, the way you run up and through doors and onto obstacles. I had problems with the jumping and collision. When I was trying to go up the platform, left/right, kept getting stuck. Took awhile to get up there. Also on the first level I didn't realize there was an elevator platform coming down so I ran right in the wall and tried to wall jump and went through wall and fell into space! haha.
