You may have noticed the new trailer and screenshots on the store page. I am planning to update to Version 2.0 very soon.
Testing has confirmed that I can load a game started in the current default version (1.4) in the new version. Still, it would probably be better to start a new game, in case any latent bugs from the earlier versions are lingering around.
I want to update the manual and do a little more play testing, then I will pull the switch!
