After a few months in Beta, the game has finally reached the state where it deserves the v1.0 label ! ːsteamhappyː
There's no common big bad bug anymore (although it may still have a few rare ones, so be sure to report them if you meet them), and all base features are there now with the Steam achievements and the completed documentation.
In the incoming months I will still add small user-requested features, and in the years to come I'll try to regularly add bigger features or do some noticeable rehauls from your feedback.
For now, I'll let the game in the Early Access state as it might still need a series of polishing, and to encourage new users to give feedback & feature requests..! :-)
