This is very good! I don't know what I can say that wont already be said; the tower defense part of the game provides a very strong base, and I have always enjoyed game that make the player inadvertently create their own obstacles. I really enjoyed looking at the cross section between the two genres, and I think there is a lot of potential to expand --either the bullet hell gameplay (new abilities like dodging) or tower defense gameplay (maybe build defensive structures too, to protect yourself from your own creations?)-- which would let them work off each other even more. I enjoyed the concept and look forward to your next creations.
