I saw that nobody has done a co-op run for any% or 100% yet. What's the reason for that?

Depends on what you mean by co-op. If you mean 2 people, you need to have irl friends who speedrun this game as well, and that's basically impossible.

If you mean using multiple controllers at the same time, It's very hard to use 2 wiimotes at once in this game (4 wiimotes might actually be faster but would be even harder). Because of how hard it would be, you'd use a lot less co-op exclusive strats, making the run sort of pointless.

4p Co-op would save barely a minute for any% but a lot more for 100%, KirbyMastah has written notes on it up to Raisin Ruins

I plan on doing a 3p speedrun of this game soon with my sisters soon.
