Crates, Holes, and Croles

Sokoban style game created in Puzzlescript

There are 10 levels. The goal of each level is to push all crobjects (crates or croles) onto all targets. The player can push crobjects, and crobjects can push other crobjects. Mind you, if a crobject is pushed into a hobject (a hole or a crole), the crobject and hobject will form a crole, which acts as both a crate and a hole.  Hobjects (unless they are also crobjects), walls, and targets, are immobile.

Please feel free to leave a comment! This is a part of a personal challenge to make a simple puzzle game every day for a week, with at least 10 levels. This is my first!
