Update 0.0.4 for Atomic Society is out now and available to download. Click on the link you received when you bought the game to be taken straight to the download page.
Unfortunately we weren't quite able to iron out the last bugs with save games before posting it but there's a ton of improvements to the game overall that we thought it best to get it out now. You can read the full patch notes here.
0.0.5 with save game support won't be too far away and a new dev blog will be coming later this week.
Any questions or queries about it, just let me know on the forum or by emailing us at firstname.lastname@example.org.
Thanks for playing!
