It’s difficult to balance, because there’s too much emphasis on the mechanics of how diving works, which most people will not know much about, but those are integral to the plot. I question why the underwater city backgrounds look like a surface city despite the fact that they were allegedly designed to exist underwater. The sound and music are lovely, though I think the whale noises become very repetitive most of the way through. There are a couple typos and/or missed words here or there, and there are a lot of loose threads which I wish I understood the relevance of. This isn’t really horror - it’s not spooky, or anything. But it is really beautiful. Lastly, I think there are perhaps a few too many moving parts that aren’t fully tracked or understood by the player without extra thought? I don’t know if you intended for the game to be longer, or more complex, but it felt like there were moving parts possibly working behind the scenes, but either we shouldn’t look at them, or we should be able to see them and also manipulate them. That’s just my opinion, though. Great work. EDIT: the casino background image is also missing.
