The only reason it has been such a long time since the last release is due to unavoidable personal circumstances. Eventually, I'll finally get back to 3-month updates to each game. But I will continue to work on the updates in tandem. The past 7 months were a mess that was not normal and not the way I plan to do releases in the future. Yes, there will be more Serenity and yes, there will be more Last Human. What most people don't seem to understand is that it is actually healthier for me to take turns working on two separate stories, so I don't get burnt out on doing one. So, switching back and forth is actually better. Yes, that does mean it's a bit longer between updates to each game, but like I said... it won't be like it was the past 7 months, as that wasn't normal for me. Once I complete this Last Human update, I should be able to get back to my 3-month schedule again. Meanwhile, just hang in there. I am always working on them ;)
