Build me a simple project that lets someone download and run a big browser game snapshot on their own computer, with easy one click style setup for Windows and Mac.

I want it to download the full game files, verify them with checksums, and then start a local server so the game opens in Chrome or Edge at localhost. Include clear help pages for setup, device checks, and troubleshooting, plus a way to resume downloads if they get interrupted. Make the Windows version work with double click scripts, and make the Mac version work from Terminal and with a launcher script too.

It should also have a local support page with compatibility checks, performance options like lower memory and higher quality modes, and basic guidance for when the game gets stuck or the browser needs graphics acceleration turned on. If you need to look up current docs or browser requirements, go ahead and do that.
