ok even though chillroom was just released (and it's amazing and I love it) I think we still need more pk maps!!
first of all, bring barrier back. even though it was really infuriating, I miss it and we need it back. if it was glitchy, if too many people were hacking, I get it. If not, it was a rlly great map and it needs to be on the server as much as city does.
secondly, if there's any way to add world save files into the server, then there's so much out there. Again, if it's glitchy, or too much work to cheat-proof it and add all the checkpoints, i get it. if anybody on the staff team is willing to do something like that, here's my main suggestion.
(take into account the fact that people would be able to download this and play through it to practice- if that's even an issue)
Just Jump

pros: it would be great for nubs, since the map teaches every aspect of parkour as it gets increasingly difficult. it's also the most fun map i've ever played, even though it goes from easy to punching-your-computer-screen difficult. Also, the map is already pretty cheat proof. It uses a iron door and lever checkpoint system, and if you were to use the gold pressure plates like the other maps, there would be no way to cheat/ no shortcuts that I'm aware of.
cons: it would take forever to set up. if, by some miracle, you actually accept this suggestion, just do checkpoints every 10 levels (there are 100 levels originally, checkpoints every level) until the final 10- then checkpoints every one of those.
also, since the map is sO LONG, even the speed runs would take 1-2 hours. If it's possible, I'd highly recommend adding it. prize would have to be massive though. literally like 100 or 200k.
AND BARRIER PLS BARRIER IS GR8
