Great for a newgrounds game, maybe reduce inertia and difficulty.
the online game is cool
only one thing I hate: too much inertia
Hey not too shabby, the aiming is a little wonky, hard to explain, I suggest comparing your aiming code with other successful 3D shooters and fix it accordingly, other then that, expand on the game.
Looks great but there is - in my opinion - too much inertia while moving the mouse.
