It's weird, maybe something go wrong when you dl the files idk it's strange if you want i can create another link for you to dl, to see if it change something
I think it was WinRar ... I extracted the files with PeaZip and was able to play it with no problem!
Thank you so much for offering to create a new link.Fun game! I like it and look forward to finding the different endings! :D
Happy to see that you solved your problem and can now play the game : )
