For other apps where the keyboard shortcuts acts more as other shortcuts I don’t use it as much.

Here's a demo of a more recent version for Flash from around 2009, which demonstrates how the pie menus serve as a much quicker alternative to the tool palette:

And of course The Sims 1 uses pie menus too.

Here's a link to the WebAssembly / WebGL / HTML / SvelteKit development version of Micropolis (SimCity), but I haven't implemented most of the user interface or pie menus yet.

SvelteKit pie menus for Micropolis are my roadmap, and I've started implementing pie menus for SvelteKit by translating my old jQuery pie menus code, but jQuery and SvelteKit has vastly different architectures, so there's more work to do, and I'm working on it in my spare time, not as a full time job.

New SvelteKit pie menus for Micropolis (SimCity), a work in progress, but I haven't written the rendering stuff yet:

Also, here's a video of the Unity3D pie menus I implemented a dozen years or so ago (there's a link to the code in the description, but it's 12 years old and Unity's approach to user interfaces has changed a lot since then):

EDIT: I know a lot of Mac users have HHKBs or whatever, so they are not actually pressing Apple keys, but I think it would make the page seem more Apple-oriented.
