I just downloaded and tried it - it works.
Again, because it's a demo, I can't do much with it, sadly.
Also, I did see your comment regarding the quarantine of this game, which I initially posted in the game's description, for some reason your comment was removed, but not really surprised, since itch.io website has been treating me and many others poorly the past 2 years.
Anyways, the game is 100% safe, like I said on the game's page.
