assuming this is the same map you're talking about
i watched this video on it and i can agree with some
the map does seem quite cramped most notably the stairs up to more minigames and such where theres little room for blu(s) to move around. armory is also quite small but some maps like the undertale one its even smaller, so it'd be unfair to give a point about that. the map is also a bit ugly but i can also excuse that since most early maps do look sort of like this. one of the things that was shown off in the video was the obby which looked pretty cool. however the deathrun actually looked so confusing, like i wouldn't be surprised if someone didn't get any of the traps after like the 10th playthrough of it.
overall i think the maps okay at most, if not bad in some areas (in my opinion). i can understand the sentimental value of the map though and understanding that most people might have fond memories of it.
though once again i only watched the video, i never actually played on the map so you'll have to take everything i say with a grain of salt.
