So funny xD
The controls were difficult for me though, having to use the right hand for up and down, and the left hand for changing modes was pure chaos for me :p. Using W S (Z S) for up down and Q (A) or E for switching modes would've been more natural to me. And then perhaps the mouse button or space to shoot.
I liked the "story" buildup and the suspense you made with the music. Awesome!
