AntSnake by MGPAlpha is a simulation game made for Game Boy Advance.
The story of the game follows scientists who have recently discovered a strange new species of ant. On their own, they seem to wander aimlessly, but together they form a new macro-organism: the ANTSNAKE! You are a researcher observing this fascinating new behavior in a lab environment. Try to see how long the AntSnake can get without crashing into any walls or into itself. Whenever the AntSnake comes into contact with another ant, that ant will join and the AntSnake will get longer. It will be difficult to handle the AntSnake in the end, but as long as you don’t crash, you’re good to go.
