yeah! about the portal. I didn't really want to dwell on it too much because I think for most people they play tourneys at least with the sky switched off.

Thanks for the kind review man! Was a re-learning curve putting this map together. From my point of view I think it’s possible to tell in terms of detail and design complexity, which areas I began detailing first, and which area I finished on.
The sky box issue is the visible lines in my portal sky, right? I never did solve that. I should have spoken to Hipshot about how he overcame that issue.
