The game - Boulder Dash - Dendy | NES

Very beautiful logical walker. One of the classic types or genres of the game. There is a miner who digs underground passages, and stones, both precious and not very, which are subject to gravity and can crumble right on you. After collecting enough gems, you can go to the next level. The level selection is very nicely shown on the map, made in the style of later games with Mario in the title role.
