Glad to hear you're looking forward to the full game! We haven't finalized the release date yet because there are a lot of factors involved right now. We're a small team (only two people) with other jobs full-time, and the amount of time/money we have for game development varies a lot. We wouldn't want to disappoint anybody by announcing a premature date, so we're waiting until more of the game is completed first.
Once we decide the release date, we'll definitely make an announcement. If you’re following us here on itch.io or on our dev blog, you'll see the news there right away. Thanks for your patience, and we hope you'll return for the full game! :)
