Crank is pretty similar to both A Dark Room and paperclips in terms of feel, also not mobile friendly at all sadly: https://faedine.com/games/crank/b39/
Not sure if it's unfinished but the power balancing was always a mess, solar panels trounce everything else by a country mile. There's a whole "set up plants on planets and receive power from them" system that I missed until I had already completed the game because it is literally 1/100th the efficiency of just making another solar panel.
Fun game though! Definitely worth a play if you're interested in clicker games with an unfolding narrative.
I'd call it finished in practice. They might have had dreams of making alternate or more satisfying endings beyond the current, but there is an effective end.
Re planets: yeah just don't even bother. By the time they arrive, your production will have outstripped anything that gets delivered. I had a bit of fun setting up huge quantities of cheap things on nearly every planet and then racing the stream of pointless supplies around the map... but I was already making far more supplies per second than was delivered and able to be used due to storage and production caps (ignoring that I had no useful reason for increasing further, after some point you just trounce everything trivially).
It's a typical incremental game-reset finish, if that works as a non-spoilery answer. AFAIK there's only one, and no reset bonus / nothing changes after it. The full story is readable through the decrypter.
I can elaborate if you'd prefer, just figure I should try to stay safe by default :)
I just remember the last time I played, I got to some point where nothing new was happening for a good long while, so I assumed I was at the end of the content.
