I myself probably wouldn't go for any glitch categories for many of the maps, but I think it would be interesting to try and I bet most others would like a seperate category for glitches.
Yeah, it was just added a few weeks ago, and I think Zen is on a break or something since I've had runs that have been waiting for verification for almost 2 weeks now. I heard someone had done a run on Facility and they might've submitted it but they probably haven't been verified yet. As for the slingshot, I don't know, you'd have to ask Zen about that.
Ok, I've been doing some runs of it but haven't beaten it yet so you don't really have to add it yet unless someone does beat it.
Why isn't Facility a map on the leaderboards? I mean, private servers are free so it could have special rules where it can only be played solo for the run to be counted. I also think it would be a fun map to try and optimize a route that can hit the levers the fastest since most other maps only have one or sometimes two paths you can take on a floor, but Facility has way more. Thank you for reading my post ig.
