Man who made this broken hack? (:P)
Anyways, definitely completely shattered one of my old hacks to pieces due to all of the new tricks I have learned and/or investigated since I made it.
I feel like this is a bit slow, but it shows off what you can actually pull off with the given resources. Also, I was able to find that you can base clip (clip into a block from its bottom) from the recoil of a shell on yoshi, as shown in the scrolling brown cave room.
