Hey, thanks for reporting. I could fix this by giving Mathic its own manifest.json file, but I'm a bit hesitant.

I'm hoping to build Worchle into a home for a variety of search-style games, so having the PWA open to the home page (which displays navigation links for all the puzzles currently on the site) has the benefit of helping those other puzzles (and the overall brand) get discovered.

It's a hard decision though as I do see the benefit of players being able to add specific games to their homescreen.

Another problem with separate manifests for games: since I'm using local storage for stats, multiple installs of different games on the site would also split up those stats. One install ensures all stats are kept together in a single homescreen bookmark.

Honestly though, I've been thinking about your comment for the past couple of days and I still don't know what the best decision is. It's a tough one.
