I really enjoy this game. And in case you're still working on this project, I think you should know that path strings on Linux (at least on Manjaro Linux using the Opera browser) appear to case sensitive. For example, the folder for that doctor images for the beginning of the game has a capital D, but the image path in the html file has a lower case d, causing those two images to not load. I'm actually in the process of running through all the paths and checking that they're the correct case. If you're interested in knowing any others I find, I'd be happy to help
