...
For some reason, there were only 2 levels, and whenever I finished the second level it would bring me right back to the first. The graphics were okay in the game itself, but the menu was kind of ugly and the 'test level' I didn't really understand. You might want to spruce up the pre-loader a little bit, too. You also might want to add some sound next time.
Overall, not bad, but could use some improvement.
