I'd rate this as an intermediate level map - it's not full of beginner mistakes but it's not up there with the top maps, either. I think there was an overemphasis on monsters, though I will say the difficulty ramped up smoothly playing on normal. The battles would've been more interesting with a fusion pistol, to take advantage of many monster's weaknesses and to get more chain reactions going. You should also make sure there aren't whole groups of monsters that congregate together without attacking. The final battle was well constructed in a couple ways. First, the geometry was complex enough to allow the A.I. to chase the player in different ways, and secondly there was a good sense of anticipation after hitting the switch, waiting for the climax to arrive. Ironically, it was advantageous to leave the green fighters alive to absorb projectiles from later waves. I would've liked to see some small-scale nonlinearity, more glimpses of spaces the player will visit later, and some cases where the player gets the high ground. Lighting was odd in some places, particularly in the interior Jjaro-themed room. There's no effort put into story or exploration, but I say that's a good thing. It means you had the discipline to stay within a limited scope.

Seriously, nice battles. Loads of fun on Kindergarten (yes, I'm a Spazeroid) and probably up there with Emerald City Citizens and Paratroopers (both from KTA). Still, Ryoko is right about differential shading. Often, it's difficult to gage what's the floor and what's a wall. However, this map does make up for it a bit by having a nice variety in textures. Great architecture, by the way. Keep it up!

I gave you a bunch of suggestions, and I'm pretty sure you didn't follow any of them, so I'm not entirely sure why you asked me to test your map to begin with. I said I would have given your map a 2.5 as it was, and I'm rounding down.

Anyway, in short: - Differential shading - Differential shading - Differential shading - Your battles are pointlessly oversized - No balance for Total Carnage; there's not enough ammo without relying on fists/infighting, and the card room is a pretty ridiculous fight on TC that you can't really win without stupid amounts of luck - KTA maps aren't really any better when they're bigger, look at Marathon 2 or something to figure out how to make interestingly designed maps with actual objectives
