Creative, original, and all around fairly smooth. My only gripe is an inability to get more ships. I lost all my live except one very early on, spending money on turrets instead of my ship. Other than that, great game. 5/5
Graphics are amazing, though I don't really feel this game adds anything to the genre. Also, I noticed the game ended before I actually destroyed the final enemy on the map (glitch?).
Fairness seems a bit lacking. In a situation where the enemy should be completely broke, and is backed into a corner, he'll begin to spam out the most expensive units possible. I don't get it.
Is it just me, or does it seem the more you upgrade, the WORSE the accuracy of the rocket gets? That, and I've noticed an annoying habit of projectiles making a random 90 degree turn. Good concept, needs some kinks worked out though.
