Click on the invasive tree to get logs. You must sell your logs using the sell button to get money for very useful upgrades. !!!SPOILER ALERT!!! When you get to the next dimension, this is where the challenge starts. You do the same thing as you did to the tree with more mindless clicking.. When you accumulate enough cash, you can buy reality bending upgrades to help you on your way for a rebirth. You can spend rebirths on upgrades used to speed the game's long playthrough.
