What kind of game is it?
This is quite a simple and straightforward game.

In this game goes to collect a currency.

In the "normal" world, trees exist as a currency. You can get these trees by clicking on the tree. Since only clicking with the mouse / finger on the tree becomes boring, you can buy blessed buildings. The currency for the buildings are the collected trees. The buildings automatically collect more trees.

Goal of the game
There is no so-called "end" because this game can be played indefinitely.

Several goals can be pursued. e.g .:

All achievements to unlock in every single world.
Buy all buildings in the game at least once.
In order to achieve all successes in the game it is necessary to start over at least once

service
Operation is only possible with the mouse / finger. A keyboard or other devices are not necessary.

The buildings will be purchased by clicking on the building. The number of buildings that can be bought / sold at the same time can be selected from the list.

The updates are sorted according to cost (the most expensive backwards) and the update is purchased with one click, provided there is enough currency.
