Had fun with the game. Haven't seen anything like it before so gj on innovation. Disliked lack of antialiasing. Lack of music was also a downer. I think only thing gameplay wise that can be improved is more simple controls, for example didn't saw any use for only one directional movement, it made game unecessary complex and haven't even used it, but since game was good even without using it, i won't be taking away score for that. 5 stars on game design ofcourse, 4 on fun (no antialiasing ruined it for me) and 4 on innovation, quite good, robust idea, idk about everything else though.
