Is there no 100% leaderboard just because nobody runs or is there some other reason?

Just to be clear - by 100% I mean all levels totally complete + all user's files, not all achievments.

If you would like to record a 100% run I would be happy to add a category for that on the leaderboards. Just submit it as any% and note in the description that it needs its own category, I can then add it.

I would do this, it sounds like fun.

Does 100% include collecting the messages?

I would assume so, since not collecting them would just make it all missions and not 100%.

Could someone update the rules for 100%? It needs to mention collecting all the user files. Thanks!

Is there a good route for 100% cause I think I remember one for any%

I think you just do every level. There isn't really a route, because there are no levels you can skip over.
