Really enjoyed this until level 31...it was a total pain in the ass. Platforms too small and you were never quite sure which way your character would slide off a moving object when you landed on it.
This is one of those Tower Defense games where it largely doesn't seem to matter what you do, as long as you're doing something. A bit like Gemcraft. It;s possible that, like Gemcraft, eventually you get to a level you need to have some actual strategy for, but I can't be bothered to find out.
It's something to do, innit? Like all resource management games, permanent resources are better than temporary resources... here they are given out randomly, and they're wat too cheap. If you get lucky, you win. If not, you lose.
Seems ok... but it is tedious to have to shove everything around. Why cant you grab hold of a block and move it in any direction while you have it in your grasp?
