Thanks! I'm having a blast working on it and it's nice to see people enjoy playing it.
Regarding scaling up to Rimworld and DF, do you mean the art assets, or depth/narrative of the world, or both? You should check out the Roadmap if you're curious about what's planned:
https://steamcommunity.com/app/688060/discussions/0/5446505913006853860/I want to work on this game for a long time, adding as much content and world building stuff as I can. So, hopefully the game gets to the same level as its predecessors. It's a very slow process because it's just me working on the game. At some point I will be making a higher def version but that's a ways out.
As for peaceful playing, you can select 'peaceful' tiles in the game to settle so that you only experience events involving friendly characters. This means you won't be attacked by bandits and such.
