I should mention the default volume and mouse sensitivity are pretty suboptimal (too jerky and loud, for me -- I need to shove everything near minimum). Unfortunately it also seems the settings reset to default whenever I look at the Settings. (That should be a Startup system, I think. It's the same place you'd check for persisted preferences later.)
Also, I'd like to have access to these Settings during the game (usually you provide a way to Escape to an in-game menu). That way one doesn't need to wait to fail before trying to edit the settings again.
From what I saw, though, it had an interesting use of the "bloody screen damage" effect, in a nice low-poly way just like the game models. I could see that minimalist style being effective. Maybe it doesn't really need the art guy yet. I think it's more important to improve the feel of the movement, turning, and firing. It's not easy to do under a deadline, so I don't blame you!
Good luck improving this later on.
