Use the arrow keys to move around to get to the dark blue. Don't touch the black or red. Try out touching other colors and see what happens. The game also gets harder as the levels go on. When you have finished the game, and you want to play again, you have to refresh the game so the score restarts.
Thanks to @super-isi who helped me with this project. Also, write a comment saying what your score was if you want to share
