Good, but lacking.
Although this is a fun concept, and the gameplay works fine for what it intends to do, I suggest you add a little more to it. I died a few times on level four and now I am writting this review, so I don't know if there are actually more then five levels. If not, I'd suggest making it a bit longer so there's more to do. I'd also suggest you make more detailed backrounds, or perhaps make the brick backround scroll as you move around? Other then that, a fun play.
