There is no tutorial at the moment 👀How far are you into the game? After you unlock The Heart, you have a progress bar until your first infinity. (ADVICE: Collect them all before doing a prestige.)
I've completed my first prestige. I still don't know how gaining an infinity works despite having already done so once, though.
The "infinity" refers to a resource amount being capped at "Infinity" (10^18).
