Played the Android port in December 2025.

There's something very “retro” about this collection of different types of puzzles - it reminds me of PC games I played as a kid, or something like The Fool's Errand. The overarching mystery is quite railroaded, and I didn't feel like the “meta” ever worked out. I also rolled credits without finding ten of the puzzles, and haven't been able to track them down on my own - and missing these seems to have locked me out of some of the metapuzzle stuff (for example, I'm missing one “gadget.”) Overall puzzle quality is impressively good, even though it's drawing on some standards, and I only caught one actual mistake in the puzzle explanations. Those explanations, by the way, are another great feature - it's kind of nice to get an explainer for puzzles I stumbled through, and there are a few geometry ones where I solved something the “hard” way and the explainer pointed out a trick I'd missed.

Least favorite puzzle type: The sliding block puzzles, not least because the hint system is basically useless for these. I'm curious if there will be so many in future entries.
