I think that I started this map over the summer but I wasn't able to finish it before things got busy. It has been on my mind since then and I finally decided to tackle it again. I had made some great progress before but this map is so convoluted that I couldn't easily pick up from my last save, so I started fresh.

Somehow I was able to complete it within a reasonable amount of time. This time, the routes and secrets came more naturally to me. Even then, I was surprised every single time that I managed to find a secret, rune, or a new route. The fact that you managed to squeeze all of this into a tiny space and generally cramped architecture was nothing short of amazing.

The hints were great. I found 2/3 secrets although I could've sworn I heard the secret chime 3 times (bookcases, nailgun, and mega health at the top). I'm really glad that I didn't look up a walkthrough or get any outside help. You said that it requires thinking outside the box but I still feel like I might have done things incorrectly. Nevertheless, I can't really imagine any other solution apart from what I did.

Even though I was a little frustrated on my first attempt many months ago, I loved the hell out of this map and it's absolutely one of my favorites out of the many maps that I have played so far. It's crazy how you managed to design something like this - really challenging and strange but still pretty fair. This is the kind of map that I'll be revisiting and recommending to anyone interested in Quake.

I think the lesson learned (hopefully) is to make things more obvious even if they seem too easy to the author himself. Originally some of the secrets were a little bit easier to spot, but then I thought they'd be too obvious so I changed it back. Of course, it's only obvious if you know exactly where to look.
And now I get purpled every time I fail at a puzzle...
