Click the OOF Head and start making OOFS, the aim of the game is to get the high score! To do this however you need to rebirth, buy items, and get upgrades! You can also go to different worlds and find new items! Items help you with OPS (oofs per second), and Upgrades help you with OPC (oofs per click). Tapables don't contribute to your total oofs.
