I love this idea. Kind of reminds me of AC: Black Flag and sending ships to do my bidding >:)
I love Adventure games. I played the demo a bit (I'm on Mac) and it's a cool game but doesn't have music. If you're up for it, I'd love to make a score for your game! I've done a bunch of orchestra and won awards for my work, and would love to give something more retro a try!
Let me know. Either way, really cool game!
