In this game there are some blue spherical creatures that live in the tree. You need to lead them to a crate. Once in the crate, each of them will give you $10. You must earn enough money to meet the goal.
To release a creature you must click on the tree, but before you do it, you need to secure their path. You can click on gray stone blocks to make them disappear. Make sure the objects fall the right way to let the creatures pass to the crate.
