The game has a tendency to feel a litle cheap and weightless/floaty at times, but it's actually pretty fun. I enjoyed it more than I expected to.
It sort of feels like Quake/Unreal if it were a Roguelike.
It could definitely use the multiplayer mode though; the version I played so single player only and no word on adding multi.
