As many people have stated, you are not given a lot of energy to get hooked on the game. It would be nice if the devs either give us more energy or preferably lower the cost of energy required to complete an action/task. I understand you can get more energy through chests/urns and even from fishing. The problem is that you are only limited in the amount of chests/urns you find on an island, which all newly aquired energy gets quickly eaten up by the cost of the actions.
