This demo has been a joy to play.
I first heard of this game from an article saying it was canceled, and as I'm myself working on another completely unrelated (and much less ambitious) game where you control a flying ship destroying pirates and navy ships in a floating archipelago, I had mixed feelings about it - a mix of "damn, it's a shame it won't be made" and " phew, glad I won't be in competition with this much nicer-looking title". After having played the demo, though, I can only say that I'd have loved to see the full version.
This is a demo done right : the user experience of navigating your ship is (mostly) slick, the simple customisation options for the ship sold me on it early on, all the necessary components are here, the less immediately enjoyable progression/grinding part has been left out, and it ends leaving you wanting more. Perfect.
So, I wish you all 4 devs good luck in your future projects, and thank you very much for making this demo available !
