Why I reckon it's an awesome game.
Okay, so it may not have outranked Super Mario World, but it's still better than Super Mario's first game. Anyhow, I love the for it's one of the only two video games I had fun playing rather I win or lose. These days it's now playable on any device, including iOS and on a saved game webpage on desktop. In case you don;t know, you can like save webpages featuring your favourite 8 bit, 16 bit and portable games to play offline. But the saved webpages can only work offline if you open them for the first time with the internet or don't delete anything on the browsing history of the web server that powers it.
