So I tried opening it in Firefox as other commenters suggested a few months back, but... it saved as Win.rar, and it's not a file that can be opened, apparently. It's not a zipped file or anything, not sure what it is. I have no way of accessing it.
I'm glad I didn't spend money on this because it'd be really upsetting to not get a response or the game access. I'm glad the web version works but I just wish we could download it :/
