I'm glad you're enjoying the game! It's a pretty ambitious project for a small team, so we're still pretty far from release. We're planning to add a bunch of content and do an early access next year, and then continue to improve and expand the game until our full release, which might not be until 2028 or later.

I feel like it's too early to open pre-orders, for now I'd just spread the word and wishlist the game on steam, and get ready for a long development cycle!
