Played the next set of maps, but still have a few more to go. Here's the video with my yammering https://www.twitch.tv/videos/457149952
The first hour was going through Ish's nightmare ice dungeons. Felt like something out of some cruel RPG dungeon design, or "Quake for people who've been playing Quake for 20+ years" (which I haven't). In some ways this is really cool, and I feel accomplished for completing it. But in other ways I wish it was more clear.
Then went through JCR's, Kamp's, Marandal's, and Naitelveni's maps. Really enjoyed the references to Ocarina of Time's Forest Temple in JCRs and the E1M1 reskin in Nait's. The gameplay in JCR's map was also really nice, with plenty of resources, as a change of pace from Ish's tense grind.
