Nah only been asked once or twice so far that I can remember
Ever since the first release last year the game has had a complete beginning-to-end route. You can make it all the way to the surface and win (though the current post-win ending itself is a placeholder). Development since then has focused on tweaking the mechanics, adding side-features, and (most importantly) adding different optional routes through the world, and the lore and encounters that go with that.
So yeah there's already plenty to do as is if you're thinking about joining up.
I actually already have the game! I just was trying to make my mind up on if this is a good time for me to start playing.
