Similar to what has been said previously, the return buttons, except the one in the mine do not work so I couldn't leave the room I was in. That being said however, the concepts were definitely really cool, going out to mine ores, then forge those ores into equipment and then selling said equipment at the store is a new look on the clicker games previously seen where it's just a case of click here and buy upgrades.
If the return buttons were to have worked then this could have been a very enjoyable experience.
