It is a lot better than the last one, as it plays more to the strength of the engine.

I could see a game being made out of that as it stands, a point and click or an escape the room. The textures aren't great, but that's just a file size thing ( I never really care about textures, they can always be made to look better, it's how the engine handles is what's key ).

Voxels do have quite a bit of potential, there's a port of Wolfenstien done using a voxel engine which looks really cool.

Squize.
