I would suggest to lower energy cost for cutting trees, stones, clay, or else lower the cost for everything for using energy so it will be better and enjoyable. I am not really satisfied witht the game.For small trees make it 5 energy and bigger trees at least maximum 15 energy same applies for the stone. Grass you can make it 2 energy maximum. Those energy cost you applied are very unreasonable. Others play for fun and doesn't want to pay. You make it free for download and have ads.
