Faster than a speeding bullet
After watching a great deal of the week long Awesome Games Done Quickly charity livestream, I've gained a new appreciation for the ingenuity and thought process of speed runners. Still, it's crazy how many new tricks are being discovered for decades old games. The latest discovery comes for 1991's Super Mario World, in where you can set off a glitch that triggers the end cutscene, by hitting a series of very specific requirements on the first level.
A game that's months older than me and we're still shaving seconds off of completion times. Amazing.
