Stacking is a third-person adventure puzzle game, developed by Double Fine Productions, where you play as Charlie Blackmore, the world tiniest Russian stacking doll. Charlie is the smallest in his family. A family where all his siblings have been taken by the Baron to shovel coal.
Double Fine Productions currently has multiple games in development besides its upcoming puzzle adventure game, Keeper.

Double Fine Productions has teased the next Time Schafer game in the latest episode of PsychOdyssey on YouTube.

It looks like a third entry isn't happening soon.
