I knew this was going to be a horror story when I started, which isn't my thing, so I was pleasantly surprised by the first bit: you have a choice to applaud or not. The lecturer notices whether or not you do. This sort of thing invariably charms me, exposing people's passive-aggressions and leaving you helpless without melodrama, and it bought a lot of good will going forward. Because The Pool does feel a bit chaotic. Part of that is the author's intent–aquatic monsters have been created at a biological research institute, and you will want to figure out why. Oh, and survive, too. It becomes pretty clear that something has gone wrong with the experiment, but it also becomes clear that your definition of "wrong" may be others' of "right." The Pool is also a bit low on polish at the micro level, but I'm impressed with the branches where you can get yourself killed.
I managed to escape, and I felt a genuine relief beyond the trivial snark of "ha ha ha I can move on to the next entry, and that's good, because I'm behind schedule for reviewing everything in IFComp anyway." I'd reached a sort of operational base for my explorations into other branches, and I was interested in not only the ways I could get killed but what they meant. The instadeaths seemed a little less insta. So the organization is impressive. There are a lot of behind-the-scenes moving parts I didn't cop to in my first forays where I did stuff, undid, and looked around. My character felt like a bit of a cipher in the process, someone who wished they could do more, and even at the end where I eventually survived after a lot of trial and error, this didn't seem to be resolved.
This is okay if you're trying to make an AFGNCAAP, but here, you sort of wonder how someone so insignificant and malleable got a job at such a place. This is compounded slightly by going too far to the other extreme with, say, "Ask XXX who would like to attack first, but secretly hope XXX says yes." This is a bit on the nose, and it's not the only one. It does feel like a lot of dialogue could be cut down, and it would've given me endurance to look through even more branches to see the full backstory. Because I'd like to.
The Pool reminded me a lot of early Choose Your Own Adventures but was a heck of a lot darker and didn't have the totally random endings that sometimes got sprinkled in, the sort that seemed like a brilliant reversal when I was twelve but seem totally unrealistic now. There's still the sense of getting shot unexpectedly or dying other ways, and these do make sense the more you explore. So there's general creepiness and intrigue here, and it certainly reminded me of people I thought were my friends, but it turned out they weren't. (Don't worry! Nobody got killed there!)
Sometimes it feels the pace is too much, and the "help bad person X" choices are too scattershot, and it even seems a bit too bland, until you realize something genuinely disturbing is happening in the background, or you get shot, calling the integrity of another character into play. This more than saves The Pool as a solid work to me, and though I recognize it's not perfect, I legitimately enjoyed it, and if parts left me confused, there were bits I was glad to patch up and realized I'd just missed.
