I enjoy the theme you've got going here, for a deathmatch map. Nice and bright, a little unusual, doesn't hurt readability. The connectivity and multi-level fights are fun too.
I think there are some "navigability" issues... catching your foot on stuff, accidentally climbing up a slanted wall when running backwards through a hall, reliably bonking your head on an overhang when making a jump, stuff like that.
Solid though, very good for a first release. I'm not 100% sure how to rate MP maps when I've just bullied some omicron bots in them for a while, but this is my best take on it.
