It makes a noise and then has buttons labelled red, blue, and yellow. How am I supposed to know what colour that sound was? Do sounds naturally have associated colours? Is this even the question I'm being asked? It doesn't say what to do or how I am meant to choose the colour.

EDIT: From some trial and error, I still don't get it. It seemed to me that blue was the low tone and red was the high tone but then I got a tone that was definitely lower than a previous yellow tone and it was supposedly blue. Potentially a bug?

My brief story: I was using that as a PWA, but encountered some snags when using it on mobile.

I cloned it and fixed those, which required switching to Android WebView instead of a PWA. I opened a PR but Paul said he preferred that I make my own fork with a new name. At that point I decided to do a full rewrite instead of just a fork (from Jekyll to TypeScript), and that's the version I posted here.

Edit: you can also clone and build the apk if you'd like, there are instructions at the bottom of the README
