For context, I'm new to Linux (specifically Mint) as a whole - I'm also new to itch.io.

How do I update? Do I just download the new game? What do I do with the old files? Do I just delete the old game? If so, how will I save my progress? Additionally: Is the toilet dimension fixed yet?

Thanks for the help, almost cried on my first time nuking Mrs. Slithers with a pineapple. 

Unless it has a folder named some form of game save within the game folder, I'm pretty certain that it isn't saving to the folder.

From my experience, it seems to save elsewhere.
