This is an amazing idea that will just fuck up your brain :)
The game is really nice and have a unique feel to it (beside the 360 camera). The ideas of twins enemies is really nice and a smart idea on how to take advantage of the concept. But I really didn't figure it out, I read the solution on the game page. So it was a bit frustrating when I didn't how to fight back at the enemies.
(At some point I wanted to know what was the shape of the room, it took me longer than expetended to figured it out)
Congrats :)
