I have the exact same problem and it doesn't work even after I extract it
Sorry my reply is so late! Unfortunately I didn't get a notification for this response. To try to help figure out what the issue is, a few questions:
What OS are you using?
Does any sort of error message pop up when you try to start it up?
Do you have the Itch client? Have you tried installing and running it through there?
Have you tried right clicking the executable for the game and running it as administrator? This shouldn't be necessary but doesn't hurt to check!
A new update was posted today in preparation of the DLC release tomorrow. If you haven't already, try updating to the latest version and see if it that helps at all.
