This is by far, one of the most fun games I have EVER played. Don't get me wrong: this game is extremely hard as well, especially starting out. You can get in game currency without paying (although you can pay if you want to) and use it to buy stuff to help you along The devs DO NOT make it easy on you. In order to unlock new stuff you have to level up. It's not easy. But I still LOVE this game. If you want a challenge, get this game :D. Thank you so much devs!
