Saw the spec cam at this angle a few times in the 1940's round. Also, i kept trying to jump along the red arrows. I dont know if those jumps are possible, or if i'm just stupid, but i think they should be clearly possible or clearly impossible. (I vote possible). Suggestion: If you do leave them as is, dont make me take falling damage by failing them (well, not the smaller one).
WIndows with glass right next to windows without glass should have a more visible glass texture. This is a particularly nasty one since the chain-link fence behind it makes it harder to pick out the wire in the glass. Suggestion: if you want to keep the glass seethrough, put frames in the closed windows.
EDIT: Also, in stage 3 I kept trying to walk into a garden straight out of spawn. I forgot to get a pic, but it's the garden near the edge of the map.
