Not marking any spoilers because, given the nature of the game, it's not really possible to spoil the solution!
This one really drew me in; I liked the *Toby's Nose*-esque setup where you can guess the solution to the mystery at any time, but to gain any basis for guessing you first have to thoroughly investigate. I enjoyed checking out the different locations, unlocking more information as I explored, uncovering potential murder weapons, and most of all learning about the deceased circus employees, their backgrounds and their relationships to each other.
So far, so good... but eventually I hit a wall. A massive, impassible wall. I'd been to every location many times; I had taken notes on which bodies I'd found, where I'd found them, and how they'd died. The problem was, there was one body I hadn't found---Vivian's. And without finding her body, I had no way of guessing where or how she had died. I also had no idea who had done it. I'd been able to concretely rule out a few weapons, and... that was it.
I finally came up with some semblance of a theory and guessed. Wrongly. Again, and again. Through brute force, I finally got the answer... and was absolutely baffled, because I hadn't seen anything that would have led me to that conclusion. (I was able to solve the after-puzzle very handily, though, because *that* information I had!)
I now know that the who, how, and where of the murder are all randomized---different players get different solutions, and it seems some of those solutions are discoverable! I really wish I had gotten a different one, because finding the clues and piecing the answer together would have been very satisfying. I can only conclude that either I completely overlooked a description of me finding Vivian's lion-chewed bones in the illusion gallery (I ended up opening the source in Twine to see *how* I was supposed to have gained the knowledge that "lions" was the murder weapon), *or* that the game had a bug and her bones simply didn't exist in my playthrough. I also am not sure if I missed something implicating Casper; I did uncover info related to them, but nothing sufficient to make me believe they murdered Vivian.
As alluded to above, the randomized solution will make players' experiences with this game vary widely. Sadly, for me, it was a game with a lot of promise that ended up falling flat.
