Congrats on submitting the first game for this game jam!
Can you do us a favor and change the download type to “Executable” and select Windows as the platform?
This is how I did for one of my games that was built for MacOS
It makes installation a lot easier on the itch.io app if you do!
Also, I highly recommend fleshing out the design of your game page. An attractive game page with gifs of gameplay and nice designs goes a long way into getting interest from players, far beyond other game jam participants.
Keep up the good work.
