Hello,

I was wondering why there is a lack of player levels on the IL leaderboard. I think this would be very fun (and I’ve already discovered some interesting glitches with Invincibility Mode). Thanks!

Player level speedruns are something more suited to the category extensions leaderboard. If you send me a video of your run along with the rules for the category, I can add a new leaderboard there.

I think custom player levels are more suited to be in a "custom maps" leaderboard, while category extensions are more focused on the main game. Take for example https://www.speedrun.com/celeste_category_extensions and https://www.speedrun.com/celeste_custom_maps

Edit: and with the same logic, IL categories in the "category extensions" leaderboard are usually extensions of the regular ILs from the main game. At least that's what I've seen in other games.
