Work with a team of distinct companions to move through a series of gimmicks and enemy encounters advancing deeper into the forest. Tap the left or right side of the screen to control a large formation of characters simultaneously. Every object in the environment is physics-driven and interacts with everything else: bullets that collide with each other cancel out, lasers that hit gears set them turning, and the player characters can use a boss's own body as a weapon by shoving it into environmental hazards.
