Controls are fine, they're really where the gameplay has any usefulness. The level is designed for the controls.
The sound, however, is a bit of a problem. I couldn't tell what basically anyone was saying, basically ever; the music/ambience always far overpowered the speech.
Also the Endgame seems to be broken. I approach, I lose control and it approaches like a scripted scene is about to unfold, and then nobody says anything or does anything. I suppose that qualifies as an end to the game?
