For many tasks, you need 40+ energy. My current max energy is 26. I can let 3 ads play (sometimes) for 9 energy. That gives me 35 energy. Now, I have to wait 20 minutes before I can complete it (but not more than 4 hours). I don't want to set my alarm to play this game... So, what do you do with this energy? click on something multiple times, then click on something else multiple times, and repeat. There is little strategy. There are few reap choices to make.
