The Tree Of Life

Tutorial:

You are growing a simple tree, every time you press the plus button your tree grows and you gain 1 more leaf per second after 3 trunks placed  you unlock branches which give you each 2 additional leaves per second. On the branches you can then add a tree top which multiplies your leaf gain by 1.1 but increases the next log price by 1.2. When you reach 12 logs bugs start attacking your tree and you need to add turrets to your branches to protect them. there is no final goal its just to collect as many leaves as possible
