So here's some feedback for you. The floor is ice, enemy AI is pretty bad, it's easy to just sneak by them because of their narrow vision and kind of set pattern movement, they should probably be hunting you down like Hotline Miami or whatever. The camera made me nauseous, maybe fix the camera on the character instead of on the reticle, or maybe make the camera lag behind the reticle a bit so it's not so instant. Grenade dudes have way too much health, the bullet time mechanic is a bit underwhelming right now, you don't get too much out of it. The enemies have basically perfect aim which is in stark contrast with their AI. Graphics could always use a bit of prettying up.
