Very, very, very basic
This game is basic. Very basic. There's an obvious pause in the music loop. Most of the graphics looks like they were made in Paint (if that was intended is another question entirely). The transitions between levels is very sudden, and will cause unfair "You hit a block", this game's version of Game Over. Generally, I can't help but feel it's been completed in a hurry.
Oh, and the stick man is floating in air.
