Drillfall

Your drill digs down by itself - you just steer it. Weave between boulders, scoop up coal, gold and gems, light dynamite for big craters and keep an eye on the fuel gauge. Cash in after every run, upgrade your drill and push past seven underground zones and four Drill Guardians to the Planet Core. Controls: Left/Right arrows or A/D on PC; on mobile, tap or hold the left or right side of the screen.
