Mining games are always fun, I think there is too much fuel at the start, there is no challenge, and I think the garage and the shop can be merged into one building, but yeah its a fun game.
I feared that the game would be too hard if I didn't give more fuel at the beginning. The reason the shop and garage are so far apart is when you have little fuel left you need to choose to go to the shop or to the garage you might not be able to go to both.
