You can seed your orbs with right click, after a few seconds orbs will be ready to collect, you will get 2 orbs for every orb seeded (You can upgrade the harvest count and speed after each level) and you have to collect 6 orbs to beat level 00, there is a orb limit you can carry at once, after reaching that limit the spare orbs will send to bank (you can upgrade your orb limit and bank size), and you will die if you use all of your orbs at once so you have to save at least one orb to live.
