A little warning! Even though Itch.io specifies that the game has been updated, the game is still the jam version. Nothing has changed.
It was my mistake. I have not updated the game, I've simply specified the game engine (Game Maker) and the OS (Windows) without knowing that Itch.io reflects it as an update. Fortunatelly the date of the files inside the .rar prove that the game is still the jam version :)
Thanks for your understanding!
