Custom Great Ghoul Duel Server

A custom server for the game "Great Ghoul Duel".

You can run it with the following command:

./gradlew run

Alternatively, you can build the project:

./gradlew build

And then run it as so:

java -DMAX_PLAYERS=${MAX_PLAYERS} -jar build/libs/GhostGame-all.jar --csstore </path/to/keystore.p12> -csp <keystorepassword> -p 8080

By default, the server will run on 8080 in non-TLS mode and the match will start when two clients have connected. This can be changed using command line flags. Use --help for more information.

You can access Great Ghoul Duel here.

To connect to the custom server, create a TamperMonkey script with the following code (and reload) or run the following in console:

// ==UserScript==
// @name GGD mock
// @version 0.1
// @description Fan Server
// @author Jason Gronn
// @match https://www.google.com/logos/2021/halloween18_reboot/r1/halloween18_reboot.html
// @grant none
// ==/UserScript==
