I remember like a year or 2 ago I was on this site with no account and went to see how well I could do on the normal mode of this game, I remember getting somewhere around 13-14 minutes. However at the time, I stopped because there was another game I was focusing in terms of speedrunning and I felt like the boss RNG on Kracko and Dedede made me feel less motivated to do it. I also did this on the 3DS VC, I probably will try to do it on the Dream Collection now. Hope I can improve my times.

good fricking luck1

Good luck :)
