I'm running Ubuntu and the game brings up an error, "Your browser does not support WebGL." But it's not running through the Web, so why would it need WebGL if it's not running through a browser in the first place??? I've run other RPG Maker MV games just fine and got RPG Maker MV myself. Is this suppose to run in a browser??? Tried it in Google Chrome, and it failed to load the "Black.png" for the menu. So, won't run.
RPG Maker MV is essentially a custom browser designed to play rpgmaker mv games. It uses a library called Pixi.js which references WebGL. I am unsure as to why you would be seeing this error however... RPG Maker MV's engine should not have this problem with WebGL not being supported
