A very nice, futuristic design. Good textures and a lot of detail. And I mean A LOT! It would be nice to see a bit more color, though.
When it comes to gameplay, at first it was really hard to navigate through the corridors. They all seemed to look very similar. After learning the layout and being able to distinguish three main rooms the fun could start. A lot of trick jumps, good scale of the map and fine item placement.
I would like some parts of the map to be brighter. Also the "grinder" was annoying as hell at the beginning :)
Overall, one of the best maps I've seen in recent years.
