The art is fantastic and the writing is very creative, but the dialog is incredibly awkward. Some of the puzzles are ingenious but others are just...WHAT?! It's like the game is stuck somewhere between Monkey Island and Limbo of the Lost. Sometimes you'll know what you're supposed to be doing but the way the game wants you to go about putting everything together is too obscure. Sometimes you're just supposed to guess until you get the right answer (doll on shelves, pipes, knocking game) which gets annoying when the game decides to make some of the dialog unskippable. The game's also got some explicitly adult humor that feels out of place given its storybook art style. It just adds to the awkwardness.
