Also, since you can play each level in the story mode and free play mode, they should have different categories as well. I play on the pc, so I don't know much about the differences between platform versions but this post is about the pc version. Personally I like speedrunning the story mode without any extras (e.g. invincibility) because it's the way how the game should be played if you play it for the first time, for example. So, please make a category for single levels in story mode without any extras and a category for single levels played in free play with any extras. Aand, super stories are also really good for speedrunning because there's an in-game timer which is really neat for timing the run. Also you can't use any extras in super story mode so it makes them kind of cheat-free :) (at least on the pc version, dunno about the other versions) So please consider making at least those categories or make me a mod so I can do it myself (can you only do it if you are a mod? sorry I'm new on this site :)

Yeah, the DS version, PC version and Wii version are very different compared to each other so I think it would be wise to separate them to different categories.

Could this game have single level leaderboards? I'd love to speedrun single levels. :)
