Demo now available
Following the tradition of doing everything the wrong way round, I've now uploaded a demo of the game to Steam. It contains 3 of the 20 endings, 5 of the 50 eras to explore, and saving is disabled.Also, a few people in the Decade Discord have asked about the game's soundtrack. Personally, I'm a bit too disappointed in how it turned out to release it officially, but for the purpose of satisfying curiousity I've uploaded it here. Since the game seems to be taking people around 4-5 hours to complete, and the soundtrack is around 4 hours, I imagine there are many parts which the average player doesn't even get around to hearing.Feel free to use any part of it yourself for samples or whatever (I did do some nice sound design in places).Read full article on Community Announcements (Last Piscean)Patch NotesOfficial
