My take is they're a little more cautious than full Arch. Arch will just push stuff because it's "ready", Manjaro does at least some testing so I'm not the guinea pig.
I don't have any issues with AUR stuff though, everything pretty much works out of the box.
Tbh is the ending of this one is as uninspired as the original game, I won't be picking it up.
Game is fairly fun, gets repetitive by the end, but I'm kinda tired of games that just end unceremoniously. Looking at you too, stray.
