The map's done finally. Took much longer than WHATPark did and I think turned out way better. We did a test run on this version on the IQ server tonight and the reception was on the whole very positive.
Upon the recommendation of a few players much better than I am (which isn't hard to be) I brightened up the map a tiny bit, and made all the lights that previously stuck out flush with the wall (I am so sick of the clip tool it's not even funny) and fixed all the clipping problems in doorways that were giving people hang ups before. This should be it as far as I can tell unless someone finds a bug within this version!
Pros: Great map. Lots of verticality, not too big, plenty of ramps and switchbacks so you're not just all running in circles.
Cons: It's a little cramped at times, but not beyond playability. Some areas are just narrower than usual. Also, (though it's warsow style), the grey/lime scheme gets a little dull. Also there is a jump pad in the centre of the map between two ramps that launches you into a very high wall.
Improvements: New colours, and maybe make that jump pad not overshoot the higher floors.
Notes: A great practice map - smooth and clean. Just minor issues.
