It's actually kind of impressive how lazy this game is. The first currency is left clicks. Then you open up right clicks, and the instructions say "do mostly the same thing you did with the left click currency." The prestige system, or "rebirth," just resets the entire game with no bonuses. The instructions say "you do what you did before your rebirthed." I guess you can buy a trophy to "win" the game after three runs. Or you can just click the X one time and leave the game behind forever.
