You can just tell how much work and passion went into this. The transmedia element is brilliantly used with the back and forth between the physical book and the digital game, which makes it such a damn shame that it can't be played on itch the same way it was meant to be played. However, all the kudos to the devs for sticking to their guns and not cutting the book from the experience, as it is a most crucial part.
Big plus also for the story. It treats children like the little people they are and doesn't dumb anything down for them. The divorce parents theme is amazingly executed, just as the jealousy and friendship themes. I really love that the game isn't trying to paint its main character as a perfect individual right away, but as a growing, learning kid. Another big point that I feel needs to be mentioned is the way it can also be played with only adults, but that it's the kind of game that makes even adults become children again. The relatable little puzzles can bring anyone back to their childhood. It's just lovely <3
