I'm still working on this one, as well! Here's some quick screenshots of the next version. The big changes are finally getting the night time skybox in place and fixing all the lighting for that, but I also removed the lowest level to try to refine the gameplay to a smaller space, and removed the glass from the big window facing the stage. I still have a feeling I'll need to redo a lot of this map, but I wanted to give things another test before committing to it.
I definitely think the second teleport area outside was a good thing to remove with the last update, as much as I liked the idea of the space. Overall the map just had too much to it, players were spread out too far. This still might be the case, especially with the lopsided layout with the stage teleport on one side, I may need to make it more central in the future, but we'll see!
