I think you should copy how dicey dungeons does it: https://www.speedrun.com/dicey_dungeons?h=Episode_1-Any-pc-steamdeck&x=wkpm6z0k-r8r1oyrn.8103pdo1-9l77pqql.rqvp407q

For dicey dungeons speedruns you can see each episode (like the different levels in this game) with all the different characters. Right now the board is all playing the same character because it's fastest but since the game tracks each char differently the board should too. Here's 2 of my speedruns I'd submit if the board got changed.
