Hi again! I unzipped your file on two computers, and I also send it to a friend to see if it works on his pc as well. And it does! It actually works, so at this point I think it may be a problem related (maybe) of your anti-virus or something like this. So I suggest you to install the game on the Itch.io official app, otherwise (if you want it in your Steam library) to wait until I'll be able to publish the game on Steam as well. Thank you so much for your support, your kindness and your will to try my work. Also your cover for your library looks amazing! Thank you!
