Decent idea. I can see promise in a game that's like Bloxorz, but instead of trying to get the block into a position where it falls into a narrow hole, the player aims their weapon in certain directions.

Unfortunately this build is incomplete, I couldn't finish off the enemies with any amount of bullets, and the grenade didn't seem to function.

Cool to see a full-3d game. Promising start.

I wished that the WASD controls reflected the camera angle, that got a little confusing.
