A wonderful little detective game where you wind up playing all sides of the story to a rather inevitable conclusion, with a cute little framing device. Definitely a fun adaptation of the character. The gameplay is nothing new, but its well-done, even if occasionally steps can be a bit opaque.

Pros: - I liked the characters. - I liked the style choices. - I liked the sense of adventure. Cons: - Many of the puzzles are awful. Some of them are incredibly simplistic, others require ridiculous leaps of logic, and it felt like there was little in between. - Some of the mind maps are incredibly unintuitive. Sometimes you have to draw genuine connections, other times you have to draw connections you *know* to be

The game itself is a pretty mediocre detective style which you can expect from the developer. However I stopped playing this game and wish I could still refund, because I just lost all my progress. I accidentally clicked on "new game", which starts a new game without confirmation, overwriting the existing (only) save. There are no manul saves. This is super stupid and annoying. Cannot recomment this crap.
