Excavation Sphere 3

In this segment of Digger Ball 3, your task is to operate a digger. On your screen, you'll notice a doughnut of a specific color resting on the ground. Below, at a certain depth, there is a visible special well. Your objective is to guide the doughnut into the well. Achieve this by using your mouse to excavate an underground tunnel. As the doughnut rolls through it, it will drop into the well, earning you points.
