Interesting game idea. But I don't think that I fully understand, because you can bascially place an endless amount of walls, blocking of all turrents. Some problems I found are that sometimes the game just resets to the main menu. The audio also becomes really weird when this happens, maybe it is played multiple times? Also, the movement is really hard to control, espacially with this flying thing all the time around you. You also get stuck on walls sometimes.
The levels seem random generated, which is pretty cool. The player looks really cute, I like his animation.
