This was cool, loved the firing mechanic, got a score of 268. Love the leel design as well, fits perfect with the mechanics, rotating camera would be nice without using mmb but I found that added to the gameplay as well.
I can imagine different enemies with different shapes attacking differently, triangles being like Kamikazes, half moon that roll over and sprays poison around itself in a small area then rolls back and chases again. lol
Great game, well done.
