Sounds like a cool idea! Sadly, I'm not very skilled at coding, so making something this complex is out of my reach. If it's any consolation, though, I am working on an RPG-themed deathmatch in which players choose between 8 classes that are commonly seen in RPGs, such as Knights, Wizards, Rogues, and Barbarian. It's mainly to complement my Tavern Brawl/Action Melee DM and test out dueling weapons.
On a more relevant note, if anyone so chooses to work on this project, I would
love to compose background music for it, since that's probably my best way of contributing.
