Tree Chugger is a two player game with one player controlling a bulldozer with the directional arrows of the keyboard and the other planting trees in an effort to save the ecosystem from extinction.

The Bulldozer creates tracks which give the player a speed bonus which the "Planter" can destroy with a special "Shroom" ability that eats away at the road.

The "Planter" must strategically create a foresty empire by using the growth mechanic to outwit the Bulldozer for as long as possible.
