Not gonna lie, I didn't understand anything about what I was doing, but I extracted so it's okay I guess.
First of all, the controls. They feel very weird and floaty, especially the mouse, that for some reason feels like driving a vehicle (like xmada said).
You can get off the map without really trying. The walls don't have collisions, so I spent my time runing away and looking at the skybox x)
Most buttons on the menu didn't work, or only sometimes.
Other than that, the game has good audio, a nice mood and the intro/outro is a nice touch of storytelling.
