2Gb of Linux doesn't seem have enough room to unpack all of the game, so I'm still stuck; unfortunately, I haven't completely given up on trying the browser version. I looked through everything some more and decided to look into the console again. I noticed that the errors were showing up as links, so I clicked on them as they showed up, trying to find the exact thing causing what I thought was a butterfly effect of errors.Opening this brought me to a blank page with nothing but the error message that I think is the root of it all:
I assume my computer is the "anonymous caller" here. Either that, or the game is showing up as anonymous. Either way, something's trying to access storage, and it can't. I cleared all cookies twice and made sure nothing on my computer was different from when the game was working. If it's my computer suddenly blocking the game from accessing cloud storage, is there a way I can make my computer allow the game to?
Moving on, I looked at the other three links in the JS console errors:In order, from top to bottom, the links sent me to these spots in (I'm assuming) the game code:
A line of "uncaught" code, whatever that is.
Code with the same error message as the game.

And, for some reason, code that doesn't seem to have anything in red, besides the "package" that I believe to be the save data that I don't have. However, the error link sent me to " callback(event.target.result); " instead of ' package/'.
Does any of this mean anything? Again, I apologize for your time, and hope this is helpful in any way. If anyone else is having a similar problem with their browser, maybe this could help them, too.
