Othergrowth

Othergrowth is a game that puts you in control of two characters simultaneously.  These two brothers are Sonny, the engineer, and Leo, the acrobat.

Sonny and Leo are on a mission to save their sister, Emma, and escape to the real world after they fall into a parallel dimension where everything is overgrown and there is little human life around.  They must overcome puzzles, parkour, and enemies in order to accomplish this goal.
