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?
