Make it into the mine and explore it! This game offers you to play for a miner, who is collecting coins and escaping the dangers. Run through the underground area and try to reach the end of it.
All mines have rails and trolleys that carry minerals to the surface. However, they are moving quite fast and if you don’t want to be smashed by it, you should not stay on their way. Also, be aware of goblins! These nasty creatures don’t appreciate people who enter their territory. It is better to stay away from them.
Finally, instead of swimming in the subterranean river, you rather use the timber that is floating across. Jump from one to another and reach the bank before the beam swims too far. While coping with the obstacles, pick up the money. In the break, you can use them to unlock more intriguing figures.
