Got an error immediately after starting the game, right after confirming the difficulty.
Error
Uncaught TypeError: Cannot read property 'resolution' of null.
This pops up in my game too sometimes when i dev in rpgmaker, usually if I am trying to switch between showing something too quickly (frames) or if something like a soundeffect has been added but not defined. I will see if the browser version works for me. My computer is pure shit, so it might not be a problem on your end.
