Use the arrow keys to move Mario. Avoid Bowser or you will lose a life. You get 3 lives. When you run out of lives, it's game over! Get as far as you can! As you progress through the game, more enemies appear. You get a level-up for every 30 seconds you survive. See if you can beat the high score. Note that the Koopa moves backwards because of an accident, and please don't leave mean comments about it.
I came up with the idea myself. Made in 2019.
