I am very very bad at this game but I can appreciate the work that went into it! Enemies that track you from a good distance away, a 3D radar, super responsive interface. I got turned around a lot and wasn't very aware of what was going on around, behind, above and below me, but the feeling of dread was there! The 4-lights in the distance was a great touch -- is it a much needed supply crate, or a monster? Really good core design.
