Seems the dev forgot to post any announcement here regarding this game, so I’ll just post it here:
We’re sorry. Zodiac Axis is no longer under active development. After careful consideration, I’m regretfully ceasing active development on Zodiac Axis. I’m enacting an open refund policy for our Kickstarter backers and beta access supporters during this time. I will continue to develop the story in the background, but no longer can guarantee a specific release date.
