Digger

Players control the titular 'Digger' that can tunnel through dirt with ease. The goal of each level is to gather up each of the gems, which allows you to progress to the next stage. However, Nobbins and Hobbins are also lurking within the levels - Nobbins are fairly slow, but transform into Hobbins which are much quicker. The enemies can only chase Digger through the tunnels he creates - they cannot dig through the dirt themselves. Digger's defenses consist of being able to shoot a single, rechargeable shot in the direction he is facing with F1 (which recharges after about thirty seconds), crushing his foes by digging underneath a gold bag and letting it plummet down, crushing anything in its path, or by collecting the bonus cherry that sometimes appears, causing Digger to become temporarily invincible.
