I love playing 10 minutes of gameplay, then having to wait 12 hours to be able to play again. There is no way of leveling up energy faster, besides 3 ads that come up every 6 hours. Heaven forbid you spin attack and end up attacking some random that holds a grudge for days on end. The other player constantly clicks revenge and keeps destroying my buildings. Devs need to limit the revenge feature to a one-time thing, not unlimited uses.
