Hello! to answer your question yes it is a bug, it is fixed, I think that in this website it's using the first version of the game, I'd like to fix it right now but I have to get to work soon, I'm sorry!
You must be registered to see the links
here's a link to the itch.io version that should work, however if you don't want to do that no worries when I get back from work I'll fix it right away
as for the story I am really glad you like it, I am not that good at coding and I had someone help me with that, I am currently trying to improve the game UI and mechanics along with a rebooted version of the story I know people will enjoy, I am just limited by my coding so I have to do with what I am given(by myself) that's why it's currently in demo
