ZX81 Snake by AdrianPilko is a new reboot of the classic snake game and runs on the ZX81.
The game is quite simple like the rest of the snake games but the format, design and production are literally different. The snake runs smooth and it eat its fruit swiftly. The upper bar shows your score and how many lives you have left. You need to progress through each level and survive, without touching yourself or the boundary walls.
