I can totally see the voice sfx being a polarizing thing, having a setting to toggle it on/off seems like a perfect compromise. For me personally, I don't think the audio mastering was an issue, I just find that cartoony sped up gibberish style ear-tickling in a negative way lol. But like you said many people love it, and I didn't grow up playing Animal Crossing so that probably explains it.
I hear ya, I've done the same thing before. It's hard enough to strike a good balance with the tutorial in a regular game, let alone in a jam when you have like half a day to shoehorn something in lmao. Dialogue is great for being written in an hour btw :)
I think I will do a post jam update to add in a settings and proper quit game menu. And thanks! It was about 3am when I started writing so the fact that anything made sense was a miracle xD I was happily surprised that most of the games this year needed very little tutorial-ization just because most concepts were straight forward, in a good way!
