Pearl (Prizzlesticks)

Severely underrated, great plot, engaging characters, interesting world-building, and surprisingly good use of motion controls in some instances. The soundtrack is also amazing. The story was especially well-written. I can normally predict the end of a plot before the end of a first act, but it took until Chapter 4 (of 6) before I puzzled it out. Even then, it was a delight to see the rest of the game unfold. A beautiful game that too many people haven't played.
