Bone Cruncher

Bone Cruncher was released by Superior Software in 1987, with a re-release on their budget Blue Ribbon label in 1990.

This game is a Boulder Dash variant. The levels are filled with dirt (which vanishes when Bono walks over it), monsters , and glooks (basically rocks with eyes). Monsters can only travel on ways without dirt and their touch is hazardous - some even eat up the skeletons. There are 25 skeletons to find in each level and specific steps have to worked out to reach them (e.g. using a glook to cut off a specific monster's path), giving the game a puzzle-solving character.
