Use Boxmen

Use Boxmen is a short 2D puzzle platformer, in which players have to collect boxes through-out 13 levels. But the levels can only be completed with the help of your friends, other boxmen who will mimic your actions. Most of the puzzles require precise timing, coordinating your and your friends movements.

Boxman can be controlled with the arrow keys to move, and Shift spawns your friends. Only a certain fixed number of friends can be spawned in each level.
