Not fun. You just hold the screen and let the train go around the ring, let the truck construct and buy upgrades. Upgrades that doesnt scale, car level is the damage. Ads every minute, between 30 to 60s ads. No visible way of earning gems in game. Not an idle game since you need to be very active to play.

I liked the idea of this game but was very disappointed to see how often forced ads happened. I pushed through them to see if I liked the game enough to deal with them. After completing world 3, the game almost crashes and sends me back to world 1, which is still completed, and I can't do anything but keep mining and not even making money off it. Huge disappointment! Will wait for more updates and see if my review can be changed.

Train glitches in the level with Big Ben. Starts going in a circle and not picking up material. The view button doesn't work so you can't see all the buildings. The cost to merge your cars is STUPI high base on the amount of material you pick up. 450k to merge cars to level 5 is almost impossible due to the amount you pick up and the coin you get for selling the material. Only got 2 boosters the speed and auto. Good concept real potential.
