Stacking

Stacking is an adventure game set in the 1920's depression era, with the player taking on the role of Charlie Blackmore, a Russian Doll whose family has been kidnapped by an industrialist known only as 'Baron', who has been kidnapping people for his nefarious purposes. In order to progress through each level, Charlie must stack into additional Russian dolls in order to solve several puzzles on each level with multiple solutions. In addition to completing each of the levels, there are bonus objectives on each of them for players to solve (hi-jinks).
