Really cool concept, don't think I've played anything like this before. The music also got into my brain. The gameplay is a bit slow though, try speeding everything up 10-50 times. The hit boxes on your units feels to big, i don't think i ever managed to doge a enemy bullet. Hitbox on enemy is fine though, no one wants a fair single player game. In total, not the best game ever made, but it was very playable. Keep on creating :) Here is a video of when i played the game:
