Thank you for bringing this to my attention. This was my first ever Twine game that I released quite some time ago - I've since switched computers a few times and I'm not 100% sure where the file still lives, though I may be able to scrounge it up. That said, if it's an issue wjth how I coded the game I don't know if I have the coding skills to fix it.
With that said, I'm very active in the Twine community, and if this is an issue with Twine itself it merits fixing. I'll do some asking around to see if I can get this fixed - thanks for bringing it to my attention.
