I just played a TDM on it with bots. Lots of fun.
It seems to me that there are two ways you could go with it. You could load it down with weapons like you got it (makes it extremely fast paced and dynamic), or you could limit the weapons on it (possibly only bullet and explosive weapons). It is up to you which you choose.
I would suggest removing the mine layer. It doesn't seem to fit with the tiny size and quick rotation of sides you got there.
I like the health and armor placement, very handy.
Spawning points (if those were designed, I don't know), seemed to be well chosen as well.
In other words: balance the weapons a bit, and renovate the textures, and you got yourself a good map. In my book at least.
Proverbs 25:8 Go not forth hastily to strive, lest thou know not what to do in the end thereof, when thy neighbour hath put thee to shame.
