I liked the visuals, I liked the blippy sound effects, and the mouse look was very smooth and had a sensible sensitivity. First person jam games can often be scary because of janky mouselook!
I'm mainly just curious why the player's acceleration is so slow, you can't really react to enemies shooting - you need to make sure you're moving fast enough before you see them, and don't slow down/hit a wall until you kill them. Led to some frustrating deaths.
Otherwise it was pretty neat, good job tackling 3D, I'm a big fan of first person shooters !
