i understand the controls very easily, i dont know why nobody else does lol?? you click the camera which makes your power go down by 10% but you get $1. the strategy to do this is keep clicking until the power is 20 or 15 percent, then click the battery to recharge and keep doing it. I guess it would be a better game if it had a purpose. Buying everything from the shop doesn't do anything that i'm aware of??
