I remade the 1997 game 'Snake' in Scratch! This is 100% pen and the game display is represented in a list which contains the data for each individual pixel. Use arrow keys to change direction. The aim is to eat as much food (red pixels) as you can without bumping into yourself. You get longer the more you eat.
If the world best score is 0, then that is because you do not have the rank of a Scratcher, meaning cloud data does not work. This sadly also means that the world best will not save if you beat it. UPDATE: Bumping into the edge no longer ends the game, and you instead appear on the other side.
