Look at the first few pages and you will see issues were found with it. Mix that with that its retired means no updates.
However, as a long time Rimworld player this is not the end of anything. The game has a fully built in dev mode still active, just enable it in your options.
It takes some time to get used to but you can turn off player damage, spawn in stacks of anything you want, summon raids, the options are extensive.
Hopefully you can find something to help with what you want, if you still struggle post here & I will try to help or msg me directly (am bad at keeping track of threads)
