Hey, not sure how you're used to working, but I saw that you're a single developer making this whole thing happen (congrats, by the way, that's very impressive), so I figured I would break these down into separate topics so they're easier for you to track.
The startup sequence is pretty slow, mainly because of the text building up the sentence at a slow rate. Could you update this to where the text is just displayed all at once, or allow a button press to display it all/skip it? I think it would speed up the startup time.
