I made this video about 3 years ago when I was discovering a bunch of bugs in this game. Most of these have been patched but some are useful in the patchless speedrun. This video does not show the bananaphone skip (aka cake skip) because I did not discover it until 2 months after I made this video. Also it does not show the new station OOB that was recently discovered.

I mentioned the majority of these bugs to the developers and they patched most of these, so you can blame me for them fixing most of these.
