This is and exact replica of what I did in my gourmand playthrough. Like seriously, its crazy. I was at THAT shelter, trying to get a red centipede, and in the process, tamed THAT caramel lizard. It wasn't with rotund world though, just normal rain world
I thought it would be too, but I've been playing it this way with my friend group for a few months now and everyone agrees it is a massive improvement. The zoom out only happens when someone misses a jump or falls off some ledge, but having it enabled for those cases is very helpful
The camera-zoom and splitscreen functionality require SBCameraScroll and Splitscreen co-op respectively, but you can disable these features by simply disabling those mods! (or through settings in the remix menu)
