It's been three years since I downloaded the demo! Sadly, I'm of the belief this project has been cancelled; the author's website is no longer available, no updates on twitter, and no devlogs to say otherwise. I do see that the page has been updated recently but I'd figure there'd be a devlog if there was news to be had.

No, we didn't cancel it and kept working for three years. And it's just released on Steam!
