very nice first crack at gamedev! Definitely going to parrot Quinten on the aspect ratio thing. I didn't do that for my game either, and it was definitely a regret of mine.
I read the "Just "enjoy" me breathing into your ear" bit so I have to ask, did you record the sound effects yourself? Very impressive if so! (I've always steered away from that but it's something I'm very interested in doing!)
But yeah, love the vibe you're going for, and I hope to see you continue your gamedev journey!
