The concept is great. I love the art and quests. But this isn't a game you can play for free. This game is designed to get you to spend a ton of money on small transactions. The developer says you can get energy by spending it. But spending 54 energy to get 5 back isn't worth it. The first few levels draw you in with endless energy. But I'm only level 7 and have been stuck for days because of no energy.
