This was actually the first game I tried to learn in a formal speedrunning context. Prior to this, I used to race Super Monkey Ball and Super Monkey Ball 2 with my college roommates. That led me to Google searching and eventually finding SpeedRunsLive, GDQ, etc. I don’t know if the gameplay got better on my stream over the years, but the layouts certainly did. Have a look at this blast from the past here.
