Enjoyed it. Great to see people still making maps for vanilla/id1. I disagree with the notion that it would have been better for AD, as great as that and other mods are, I still enjoy the purity of "normal" Quake, both in gameplay and visuals. I'm probably a bit odd in that I actually even prefer it.
Anyway, some nice, clean, classic visuals. Thunder ambience didn't bother me, although perhaps it clashed a bit with the skybox. Gameplay-wise, nice flow and interconnectivity, nothing too difficult, although I'm a bit rusty so did take a fair amount of damage. I liked the progs.dat additions with ladders, breakable boxes etc. Although I did initially mess up when extracting the files so the progs didn't load. Didn't play that far before I realized something was off.
Playthrough on Twitch (feel free to ignore the in-jokes towards the end)
Looking forward to more (id1) maps from you!
