Game concept:
- Same as snake, player is a dark colour dot, and eats apples.
- Player eats purple apple, gains speed. Player eats white apple, grows in size as a blob, light colour (as snake body).
- Player still has a "head" in dark colour in the blob
- Player can "eat" other players by having its body rolling over another player head
- Player can create white wall behind him by letting go some mass
- Player dies if its head hits a wall
