Games with longer levels mean that you have to keep pressing the arrow down to find the level you want. It might just be for mobile.

Why wouldn't you just make those ILs instead of full-game categories?

@Walgrey level leaderboards suck

@Act7 100% mobile only, I'm scared for people submitting to MKFusion now >.> (there's around 700+ ILs with more on the way)

How does a game have that many levels?

It just does, they're all custom levels made for mario kart over the last 12 years
