Mine Shaft

The Good
Mine Shaft was the only PCjr cartridge I own. The goal is to take gems by avoid ennemies through ten levels. I suggest you to play with a joystick instead using a keyboard. Some ennemies can be destroyed by shooting them. Only one ennemy is invincible to your shots. I can play 20 minutes to Mine shaft.

The Bad
Using a keyboard to play is not good because you'll use I, J, K and L keys to move the shaft.

The Bottom Line
If you like Pacman, you may want to try it... with a good joystick.
