In Digger Man, your task is to dig a tunnel whilst being pursued by Devil Dan. You can take a break by dashing back to the surface, where Dan is powerless to follow.
You choose your own control keys, which I thought was a very good idea.
The game, which loads in two sections, is a good easy-paced introduction to electronic gaming and particularly appealed to my eight-year-old son.
Devilbirds is ideal for the "blasters" among you. From the floor of a dark cavern, you fire away at a winged creature who glides slowly about above you, occasionally unleashing his own deadly laser in your direction.
Another target for your own weaponry is the bat-like creatures hanging from the cavern roof, which turn out to be embryonic Devilbirds.
