Thank you! The sound effects and the polish are what I spent most of my 3 hours on, so I’m glad it’s noticeable.
I’d also like to mention that there is a win screen, if you go back to the submarine after exploring everything then you get said win screen. I did write it in some text at the start, but that’s pretty easily missable since it disappears fast and I didn’t make it very clear that you needed to return to the submarine for the win screen.
