This is a nicely made transportation game. You're a mole who drives a tractor. Your traktor has a trailer full of cargo. You need to deliver it to the end of the track without losing it on your way. You can switch some road blocks that will let you go different way. Do it pressing Space. There are spots where you can load some extra cargo that will give you more money if you deliver it to the finish. Press Shift to drop cargo at these spots.
