Mine would have to be Runescape. One day I'll get around to speedrunning it.

Mine would be when I hit the WR on a game (meeblings) while practicing the run. I was never able to get it again.

Could we please have each individual level added as a category in the 'Levels Leaderboard'. Proof could be provided with a screenshot showing the time, as well as video evidence.

Idea: speedruns for beating each boss, like a category for killing KBD and such like.

It's in the title, simply a request that each individual act could be a category as well. For example, 'Blood', 'Ice', and 'Steel' having their own category.
