You can't beat Brineybeard with whetstone so I think that might kill the run. Youd have to exclude him from the category all together

The tutorial speedrun is in the category extensions already I think

It most likely will be a separate category, like how legacy and 1.1+ are separated, or how 1.0, 1.1 and 1.2 are all separated for boss ILs.

Post DLC, the ILs will probably have a 1.3 category or something like that. But the only way to know for sure is to wait and see

I’m a simple runner. I just like Simple

I’m probably good enough to do regular or expert runs, or at least I could practice and become good enough. I just don’t really want to

And no you can’t finish the game, but for full game Simple runs timing ends when you speak to king dice, rather than at the credits

Make sure that in your LiveSplit settings you are comparing against Game Time

I think all mods are not allowed
