VERY FUN GAME! frantically dropping weapons onto your ship and trying to rotate it is loads of fun. I never needed more than one engine though so there wasnt much strategy to ship building. maybe the more pieces on your ship the heavier it gets so the more engines you need? also wish projectile speed scaled with ship speed. I ran into a bug where you could have floating parts considerably away from your ship but they are still attached and work. if you take off a rock part with a gun part on it, move the gun part, attach the rock part, and bam you have broken the natural law of the world lol. this game would be very fun with additional enemy types and part types. the arrows pointing to enemies really helps. I got stuck on level 2, no matter how many i destroyed and how many times it said it was going to the next level I was always on 2/5. fun game. Art and audio was understandably lacking a bit but the gameplay makes up for it.
