Not sure how exactly to classify this one; Visual Novel doesn't fit, and though it is puzzle-focused, it's not quite a Point-and-Click Adventure, either. In any case, there's a nice balance of puzzles with story, and aside from one that was a little obtuse and another that my brain just isn't wired for, the former were pretty reasonable. The latter will tear your heart out, but if you're up for that, it's very well-written, though told without a single word. Saying much more would give too much away, but what really drew me in was the charming artstyle that's just perfect for a gray autumn morning.
