So I just finished this map and I enjoyed it a lot. I think it's a bit easier than Flag Memorial, but the design is interesting. I like the art show room, and the puzzle was well done and not confusing. It feels like if this and Flag Memorial could definitely fit together in a new Duke episode. This could make a good first or second level in the episode, with Flag Memorial possibly being the last.
I had a lot of fun. I played on CGS and killed all the enemies and found the secret. I recommend this map! It is a fairly large city map that feels that the alien bastards have taken control over it. It has a similar vibe to Flag Memorial, so maybe it is meant to take place in the same country? I'm not sure. I like the choice of textures and the clever use of sprites to make the world look how you wanted it to.
Here's a couple screenshots of the art show building and a cool TV in another room:
It seems I didn't run into any of the problems from before that others mentioned when running the latest version of the map. I did have a crash happen that I was able to replicate twice here is the spoiler:
There was also one bug that I noticed and took a pic of seen in this spoiler, otherwise I didn't find anything major:
I do think there are some areas that are blocked off to the player that maybe don't need to be though. I would recommend maybe making some of the water areas able to swim under for more enemies and secrets if you still consider it WIP.
Anyways, if this is your first release before Flag Memorial, this is a great first effort! Well done, and be sure to keep up the good work!
