if you want to speedrun you gotta buy the game. that’s pretty much true with any game. there will probably be like 1 demo category but it will be so much more worth it to just buy the game

Players have done runs of the Demo, It's unlikely that am official board will be made for them, but there are some google docs out there and runs on youtube. The WR, as far as I'm aware is:

The demo is actually a little different from the actual game, and there are demo categories in other games that have demos, so maybe just wait and see. You should just buy the game though, its definetly worth it.

But also a demo speedrun would still be cool for people who maybe CAN'T buy the game.
