This has to be the craziest map I've ever seen.
Other than the lack of a playerstart and the lava (read instant death) at the beginning, this is alot of fun. Although it could use some textures... Try a rock/metal/Egyptian 'theme,' making sections of the slide look different (yes, I do realize it's a WiP; just my opinion). Even better, arcade: shoot as many monsters as you can as you speed past (preferably w/ rockets.)
Seeing as you really haven't told us much about what you want this to do (other than uber sliding...), I don't know if this is what you planned to do or not. So with that, 'my two cents.'
Did I mention this is fun?
