Not going to review everything, but here's some thoughts from what I enjoyed the most!
Great atmosphere. The HL2 citadel vibes were off the charts! Loved the use of teleportation in encounters, always had to keep on my toes and strategize when entering areas. Ending was really fun pace swap as well.
This was a really cute joint. Loved how you gave the Lightning Gun almost immediately, it was fun to be able to strategize when and where to use it. The whole art gallery gimmick was also done well. Good stuff!
Colossus
Holy shit! That was something. Big dumb fun. Only died once on Skill 2, I'm pretty proud of that. Can't think of much else to say, really blown away by your progression from your first map to this one.
Loved it. Felt like a mini Metroidvania in how gaining both the first weapon / explosive pack opened up a bunch of paths that felt nonlinear and boosted a sense of self-discovery. The ending got a bit wild and esoteric, once you start throwing in those Freedom Planet booster gates... but not in a bad way. Imo the final fight could have used those in some kind of interesting way, but it's no biggie. Pog map.
This was really neat, and the gameplay was super fun, as I've come to expect from you at this point. I loved the use of funcs to open up that second area, and the way that the indoors area came out into the void. Architecture in that one bit felt really inspired too, well done.
A new high in quality for your stuff. Big fan of the beginning few areas, the visuals are super tight. But once you get a quad, there's kinda just those zombies dumped onto you? Feels a bit weird, but the later pent+quad room was very cool. More of that first bit pls!
Honestly one of the few times visuals have knocked me on my ass in Quake. Unlike most of the other maps in this pack the scale is just right, and the combat comes at you at just the right pace to not feel haphazard in it's approach. Ending was well put together, ammunition / health balance was just right. Only thing I can nitpick is that it could have used a few more (or more interesting) secrets.
