Topple Drop

Topple Drop is a game in which you click on blue cubes and temporary (inidgo/bluish) platforms to make red cubes fall in the grass below the platforms.
How to Play:
Try and get the red cubes (monsters) to fall off the platforms.

You can delete blue cubes and temporary (indigo/bluish) platforms. You must prevent green cubes from dropping.
Sound easy? At first yes, but it gets harder.
