The Plucky Squire
Storybook characters discover a three-dimensional world outside the pages of their book and must jump between 2D & 3D realms to save their friends in this charming action-adventure.
The Plucky Squire is indeed very charming. You play as a young squire from a book series going on an adventure. The puzzles are often quite simple, but always satisfying as you find ways to manipulate the story being told.

I found the pacing to be quite slow, the gameplay sections often don't last very long before being interrupted by a bit of story. Fortunately, the game's charm and style make up for it to make this game definitely worth playing if you're looking for something new.
It's not a challenging game either, don't talk to Minibeard if you want to solve the puzzles yourselves. It's also fun to play with the puzzles to cause all sorts of fun effects in the book.
The game is not too long either and keeps introducing new mechanics and ways to play.
