This is my idea, comment on what you think about it. Of course, use the arrow keys to move. The purple balls are supposed to be coins (I did not make it look like a coin cause it is an engine) If you do not collect enough coins and touch the edge of the screen you lose. And finally the aim of the game is to reach Santa's slay( I did not add santa's slay lol)
If you played @awesomebricks1 corona dash you would realize the players code is similar to it.
