It has levels! And more are coming soon, but not for a while... I have made the fireball on the offline version so I am going to copy it and send it here hopefully... Use arrow keys to move and jump. Collect the coins. Jump upon Goomba enemies (twice!) to beat them. I know it says 0 lives but it's really 10; if you want to change something, go ahead or I can try to do it. Are you feeling a little mischievous? Press the letter(n) and you will slingshot to the last level. DO NOT PRESS LETTER (C) Here's a walkthrough: https://www.youtube.com/watch?v=ONtHRrN-cDQ
