Super polished game! I was astonished by the visuals too! Really cool work! :)
In my first playthrough, I just rushed to click Start Game without reading the tutorials, so I was a little bit lost at first, but, after coming back to check it, it all made sense (if you're looking to extend the game in some sense, maybe the UI should be self-explanatory in a way that it feels more natural to just click play, but, even then, really cool game, congrats!).
