This is a series of videos to help speedrun this game in the most optimized way that was found so far.

A lot of those tricks were discovered way back when by Trevor Seguin (see other guides for his segmented speedrun on the GC which is still very relevant to this day).

A special thanks to Sshplur for sharing some of those tricks with me.
