It's pretty neat, particularly for a side project. The controls are something to get used to. When you're walking, using the mouse to turn is very sensitive. When out in space, using the mouse is very plodding and barely moves. Also, it's very easy to walk right through the hull, and then you have to respawn your guy. That said, I enjoyed running over the engineering crewman on the way out the shuttle bay. "He's dead Jim". Whoops.
Nice work, though, seriously.
