I kinda hoped there would be more regular stable updates, rather than their nightly system (which is very a good concept, but doesn't appeal to me).
I'm just waiting for the moment they decide that what they've done so far is worth releasing as a full version.
And that might be a while, because from what they've shared on their DevBlog for the last half year, they've been completely reworking most aspects of the game.
I sometimes play in the meantime, but I find progression to be too slow and boring at the moment, which is something they're working on a lot at the moment.
