This game is a total meme and I honestly have no clue what challenge mode is, but I'll look into it.

Alright, implemented individual courses as ILs and challenge mode all levels as a category.

Can you add each challenge mode levels separately?

Can you add a 100% category. It would be all Challenge Mode All Levels but completing "Play The Show" Easy, Challenging, and Extreme.

Sorry, hadn't seen this thread until now. A 100% category could be added, but like @Silo_Simon said, it'd include all costumes/characters etc.

Well it could be 100% and 100% solo.

to add on to this, maybe a good middle ground could be an "All Episodes" category where you have to complete easy/challenging/extreme in one run. Could be easier than having to unlock everything (which would include all ballsy trophies if it was really 100%)

There could be NG or NG+ category like in the other Wipeout (TV Show) games.
