Debido a errores en el código, recomiendo hacer clic en verde 4 veces al iniciar (sin que aparezca la bandera roja entre medias). up and down arrows to move the objective of the game is to jump up and collect points. How you collect points is, when you touch a star your score will increase. The 1st star is worth 1 point, and for every star the amount of points collected increases by 1 point. If you hit the red line it's game over for you! so watch out, and have fun!
