The game - Banana - Dendy | NES

One of the many variants of the Boulderdash game with digging in the ground and collecting diamonds and simulating the attraction of the earth. In the title role - a mole, seeking to get close to his girlfriend. It differs from all other games by focusing on puzzles, since you can only dig to the right and down, you can’t go back and climb up except along the stairs intended for this.
