From Emanuele Feronato: "Back to early 1990 – 1993 to be accurate – a very interesting game called Pyramids of Ra was published for the Game Boy console.
The goal in Pyramids of Ra is to clear each stage of every tile, while also managing to return to the starting point. Players can move one tile in each direction (up, down, left, right), although it is possible to “jump off” the playing field, as well as the possibility of destroying the incorrect tiles to trap the player or render some tiles inaccessible."
