Crusher is an adventure game built out 25 rooms arranged in a 5x5 grid. Each room is a level in which the protagonist attempts to solve the problem in each room; this involves avoiding monsters, pushing boxes to clear pathways or trap monsters, gathering gems, oxygen, or quest items, saving friends, and capturing the evil Mr. X.
Each move costs the player oxygen and touching monsters will cost a life and reset the level.
After accumulating 10,000 points, the main quest becomes available: the player must find a map, rescue Eve, find Ted, find the combination to a safe, find the safe, and find Mr. X. This is quite difficult as each room resets once it has been left. The player must decide carefully which room they want to venture into next.
