Thank you so much!
Yes, I definitely want to experiment with the ability to scan and catalog every kind of thing in the world, making knowledge a valuable resource and thus emphasizing pure exploration. For now, I think it would be wise to focus the game's scope on submarine only, but I do love the idea of having various forms of traversal as a way to open things up to even more variety.
I really enjoyed watching your stream of it. And I hope you'll revisit it sometime to see what you missed. As it stands, there's a small yet complete game here. Of course, the game doesn't communicate these things super well, so I'd be interested to make that more accessible if development continues. Nonetheless, I'm glad you found it interesting and see its potential.
