You should know how to play this, but in case up=up, down=down, right=right, left=left.You die if you hit a wall.when you die hit the green flag to start again.
I made this. Not really hard. Feel free to change the speed of the snake by going inside and under the flag when it's clicked at the end; there's a move of 5 steps. That's the speed. Tell me your high score in the comments.
