Use the arrow keys to move the little blue circle. You cannot touch any object. Green triangles spawn on the right, but they are very easy to avoid. Red dots are the most treacherous enemy because they spawn near you when you are red. The Big box when it comes, it releases 4 little box. Lines spawn under you. These are the black lines. The heart moves aimlessly.
Thanks to Dan9900 for the basics. I will try to add more songs. The high score list has ten spots. It appears before and after the game. It may be glitchy. Good running!
