I tried it out, and this is my feedback:
A lot of bad seams on the textures here
I don't really see the use of this, due to the small size making it bad for a quick getaway. I guess Spies could use it, but they would probably rather use the window, as they will be able to see what is waiting for them below...
This Ammo kit is a bit too close to the battlefield, not good for Engies. I'd recommend moving the small kit up here.
I don't really see the use of this building right here, it is too open to use as cover, and too far from the point to be of any good use.
I think the map as a whole is a bit too small, a Scout could clear it in seconds with no effort. Also there is no water or health kits, which makes Pyro a much more dangerous class to deal with. I think that with some good improvements, this would be a fantastic map to play in....
Thanks ya'll, probably would change these things in a2(after gameday)While feedback is usually helpful, you're looking at all of this from a single player's perspective. Also, texture issues are of no importance in an alpha, especially a1. The drop down route is useful because it adds an alternate route, which is almost always good(most rooms should have at least 2 entrances/exits, but no more than 5).
Ammo kits are not just for engines. Any class could run out, even in arena. Not to mention, moving ammo close to spawn in arena promotes turtling, which is generally frowned upon in arena anyways.
That building, again, provides alternate routes and height variation, which makes the gameplay more fun all-around. I don't see why you would want Dr_Felix to simply remove it.
As for the healthkits, I do agree. Even though the idea of arena is to make staying alive a task, healthkits are essential so that the team isn't entirely reliant on medics and such.
Had a quick fly-around because there were a few detailing niggles I wanted to point out:
Your roofs are awfully thick. Ideally they would be no thicker than 4 units; these ones must be about 16.
This vent is floating...
... and it's only on one side of the wall!
The wooden beam on this building needs its texture rotated by 90 degrees. Also there's a wee bit of z-fighting between it and the lower roof of the building beside it. (Also pictured: more of the aforementioned roofs.)
Small complaint, but these windows look a little strange. Most likely because they've been rotated 90 degrees.
