Mechanics: Very cool idea with the multiple windows and a timer on each one of them. Multiple weapons are a nice addition, though the "homing" gun seems to just spin around the enemy, unable to hit anything. The enemies are all different, which is a good thing. Unfortunately, due to the size of the rooms, fighting two of the shooting ones was almost a death sentence, and the "spinning star" enemies (not sure what they are) just flew to the bottom right corner and got stuck there. One thing I'd change is blocking the exits that lead outside the map boundary. I died once because of that. I also once just disappeared with the room I was in, and the game didn't end. I'm not sure how I did that.
