I've only tested the first map, but it's pretty cool. I didn't mind at all paying to support the developer. I will say though, that if I operated one of these machines in real life, there would probably be accidental fatalities. lol.

A very simple game but will teach the controls of the digger portion of the excavator. The new 3rd level is broken though. As soon as I lift a piece of dirt my excavator starts spinning out of control. At the current state I would not recommend this though.
