Welcome to Super Mario World! You play as Mario in 3 super easy levels (it was a game test, too) to save Princess Toadstool who is NOT in the game, neither is a castle... Errors: -If the game lags, I'm sorry, but it doesn't crash the game like the block change color effect -I am stuck on moving Koopa shells If you know another glitch, mistake, or failed art, comment it and I can fix it :)
