Three chambers of easy-medium difficulty, two of which are cooperative campaign chambers modified for single-player. The remaining chamber is a modified single-player campaign chamber. Companion cubes will replace your cooperative partner.

BUGS
• In Chamber 1, it may be hard for the cube to perfectly land on the button. Can't really fix that.
