Suuuuch a wonderful idea with a great execution, I just think the pacing is a bit off. This game would benefit the most from a run based approach, where each wave is much stronger, but you get your new units way faster, this would make the game more intense and would promote playing more than once. Still, I really enjoyed it, but after some time there was like a 5 minute period when literally *nothing* new happened. But ignoring that, I absolutely love the genre combination you managed to make here, the graphics and music really fits together, and the gameplay is very smooth. Really good job, awesome entry.
