Fun game idea and tricky with the controlling. I liked that the heads had different weapons and each can run out temporarily. The need to change heads both for "ammo" and for aim while moving at the same time added some complexity. I can imagine you can develope quite a lot of skill in this game with practice. The one thing I didn't like was switching heads with the scroll wheel. Perhaps it's just my mouse, but the scroll wheel isn't completely predictable. Good job with the game :)
