1) You could set them in world “on start” script
2) Sure? Make whatever kinda game you want! I mean, don’t make something fascist or racist or transphobic or whatever, but that’s more a general thing and not specific to Mosi
3) You can export your rooms, resize the world, then import the rooms again - tho I should probably make resizing less destructive at some point
4) Not explicitly, but you could get creative. The point is to create worlds to explore, so I didn’t put in explicit ending or game-over mechanics.
bug) I’ll take a look at this when I have the chance - hopefully this weekend
