Do you think you know everything there is to know about Super Mario World? I thought I did until I saw this video.
Apparently in the last special stage you can collect green berries with yoshi that add 20 seconds to your timer, since it is a really long level. Yet, the fascinating trick is that if you use the berries right you can reverse time to a point before the song speeds up. Basically allowing you to speed the song up multiple times.
Amazing isn’t it?
