Super Box Bot's Package Push

Super Box Bot's Package Push is a puzzle game inspired by Zachtronics' Opus Magnum. Your task is to ensure that every package is pushed onto a goal square, through programming a set of robots.

The catch? Each robot is only able to execute a looping set of instructions. So, you can't hard code the exact path for solving the puzzle, you have to somehow fit it into a looping cycle.

Let me know what your favorite puzzle is!

This is my entry to Ludum Dare 47, a game jam with the theme "Stuck in a loop."
