The roguelike elements, as far as I can see, are random weapons and procedurally generated maps. It kind of reminds me of a 3D Binding of Isaac. The graphic style creates a good atmosphere in my opinion; I generally look at games with voxel art a little warily, but it works here. It's currently in beta, buying it now gives you all the updates and the final game when it's done. I admit I haven't personally played it yet because I've got a bit of a backlog of games at the moment, but I've had my eye on it for a little while, it looks like great fun, and I'd love to see it on here.
Paranautical Activity is a crazy fast paced voxel roguelike FPS set on a ghost ship.
