Hey I hope you don't mind a bit of constructive criticism: you should look into getting a pop filter for your mic. I'm very sensible to pops and esses so it might not bother others but it's a very cheap upgrade that you might want to consider :)
You can also experiment by placing at a 45°angle (point the mic towards your mouth, not your mouth towards the mic) and placing it slightly sideways. It'll help with sibilances and pops.
Anyways, thanks for sharing the video, I was actually looking for an overview of SvelteKit's features.
Definitely a little rough around the edges (the real-world application has bugs), but it is public beta, so it's not surprising.
