Water is ok, but I felt that lining the whole bottom of the map with it was a bit much. Water kinda ruins gameplay when there's that much.
One theme continuity problem I found: where you have the moving platforms over the fog, there is another floating platform beneath them with the light emmiting from the bottom of it.. it didnt really fit in with the Gothic theme IMO (small point really)
like the overall style tho, and it's nice to see ppl still use just ID textures!
