Sharpee.Net
Sharpee has it's own home outside of github now.
Visit https://sharpee.net/.
There are quick start and author guides along with the beta port of Mainframe Zork aka Dungeon.
The platform is also in beta and can be used to create stories. I only have the thin web client implemented, but electron, React, and screen reader clients are on the docket.
You can report issues at https://github.com/ChicagoDave/sharpee/issues
I hired a fiverr graphic designer to make a logo and banner and I'll add those when they're ready.
