Hi Stray Speedrunners

Firstly, I'm new to the speedrunning community but will start with this game :)

I am looking through the leaderboards and in the individual levels I see that there are two categories - 100% & Any%. However, in the first three levels there are no memories (in level 3 it is unmissable) and no badges? Are these sub-categories necessary or is there something I'm not aware of?

It's just because of how the website works, nothing to do with the game itself. You can't create a category that only applies to some of the individual levels, it's all or nothing. My guess is 100% for those first few levels will just be left blank, and all the runs will be submitted to any%

Exactly what Delrus7 said. The site doesn't allow us to apply categories to select levels, so we'll just move any 100% runs for those levels over to Any%.
