Wow! Great progress from your last game. I enjoyed it a lot - got to level 5. Definitely an interesting take on the shooter mechanic, turning the world instead of the player. The kills were very satisfying and friendly fire for the enemies was a nice touch! It does get a bit repetitive once you get the hang of it, so I'd encourage you to add more interesting enemies or powerups or obstacles/level layouts to keep the spice. I would definitely play an upgraded version!
