Good job
Simple, but enjoyable and well designed. The levels had a decent amount of challenge that didn't require pixel perfect jumps to complete. It was also nice that all the areas gave you enough time to view your surroundings and figure out what to do, so the player doesn't require either clarvoiyance or trial and error to complete levels. The bonus levels also mixed things up nicely, yet still retained the core aspects of the game. An excellent work overall, though some might find it a bit too simple.
