Really nice game, soothing and beautiful atmosphere.
Really good job for your first game ! :D
One little point though, I played by downloading the Win version and it's in a Debug mode. Means that when playing, i can see the console and errors haha. I never used Godot but I think there should be a way to build your game in a Release mode instead of Debug mode.
That little point aside,
Again, congratz on this submit ! (>w<)/
