Really cool throwback visuals with a good music track playing that fits well. A few sound effects seem a bit out of place and loud, like when you pick up a civilian. I think the controls are a bit over complicated though. If your point is to give the player that much control over the movement, I think possible utilizing the mouse buttons might be helpful. Using the WASD, Space, and V all at the same time gets pretty cumbersome. I like that there is the 6 degrees of freedom(I loved playing Descent when I was younger) but I didn't really find a point to using Q and E to roll. Good stuff though, certainly has some really cool stuff implemented here!
