This turned out well and I hope you reflect on the experience as a positive one... You should be glad to have put something out there and for being part of this jam.
The songs were charming and quirky and the sprite work is a plus.
Also... The crackling you hear is a bug in Godot's HTML exporter. Either we have to wait for Godot 4.0, or edit the HTML files after export. (Not tried this yet, though: https://3p0ch.newgrounds.com/news/post/1148893)
Play any of my games on itch and you'll hear it (on Chrome, that is.) Certainly annoying but hopefully that workaround, well, works!
