The controls are just flat out nonfunctional. I don't think the developer has ever attempted to actually run/play this. I don't know how that's possible, but it somehow was managed.
Very simple example. The PDA which is needed for every game function has no back button, doesn't use the mouse, and still has you move while navigating the menu with the movement keys. And again, NO BACK BUTTON, with multiple submenues to navigate through.
Also the default mouse sensitivity for turning the camera was zero, literally 0.0, meaning the camera doesn't turn.
I don't get the point of even posting it in for people to see in this state outside of screenshots. It's not even close to being able to be playable on the most basic of levels.
