Good game. But the waiting for energy is more than annoying. You find some time to play the game and you can play only 5-10 minutes because energy has consumed and need way more coins to buy more, except of you have a membership by paying real money. People download action games so they can play the time they want without waiting like building-farming games, and you destroyed the main reason someone would play your game. delete this thing & I'm sure more people will continue playing your game.
