The mechanic is great ^^ The idea of making the rotation to sensible to force the player to move to aim correctly is amazing. However, the back squares only being killed by the the yellow projectile throw me off a bit, I tried to attack them with the blue guy as well. And in this kind of 2D game it's best to make the ennemi hitbox smaller than the sprite to make the collision more fair in the eyes of the player. I'll look forward to see what you will do with this game if you intend to improve it ^^
