Godot is really interesting. I wish I had time to play around with it, but I transitioned to an outside kid (adult).

Oooooooo awesome!! Also a side feature maybe we can play against other players boats in minigames ala N64 Mario Kart via local couch co-op and online co-op. Also a gamemode for battle mode where we each have cannons. Could see that being insanely fun!! I would play it everyday. Even for the regular calm sailing your game seems to be going for. I predict it will be very popular on Steam
