Some other ideas: 100%, unlock everything. FNAF area, key cards, weapon of ultimate destruction, get all the eggs, kill eggplant bird, unlock the ability to do both endings (open both doors and get the lime elevator open). Time stops when the ending screen to one ending shows up.
All Endings, get all 3 endings, Good, Lime and Meta (Meta being to just show the file of the meta ending)
Behind You, get the drone then get the weird figure to show behind you as fast as possible. (maybe not this one bc the figure is very RNG related). The figure shows up if you look behind the player after activating the drone, it's about a 10% chance.
I think it would be cool to have category extensions speedruns, there's a thread of suggested ideas here: https://www.speedrun.com/badgob/thread/w4qs0 and we can make a new thread when it gets created. I don't mind managing the category extensions leaderboard if the current moderators are busy. Basically, I'm bored and need something to do lol.
