Interesting concept, lot of discovering in this game. It's a like quick reaction puzzle game, make the most of the lucky shots (both incoming and outgoing), duck, jump, recoil, enemy position. With more platforms, weapons (faster ones, ones that are affected by gravity?), this could make a good multiplayer game. Looking forward to the full version, expect effective interface and more randomness that can manipulated into a planned event...man, I feel smarter just by playing this.
