I played Pulsar's map first and was a bit apprehensive about jumping around as I thought falling into the void would mean instant death. Also it took me a few moments to make the slopejump connection, which was a pleasant surprise - movement tricks being actively encouraged, even necessary to proceed. I don't need an excuse to trickjump! Was a bit stumped a couple of times when looking for buttons, so took me a little under ten minutes.
Sock's map was a bit more interesting visually, although a lot easier gameplay-wise. In the end I had discovered all but one of the "secret" buttons.
Interesting change of pace in this theme I guess, although exploring for the sake of it kinda takes away the fun part of exploring, in my opinion. That is, discovering hidden areas or items and being rewarded in one way or the other, either in gameplay or exposition of storyline elements (not really relevant for Quake). Still, good effort.
