Looks like a browser game that wasn't properly flagged as such. I can see an index.html, but I guess the upload wasn't flagged as an HTML upload, so itch doesn't try to embed it. Changing that property on the itch page might fix it, though you can't re-upload the zip so you need to be careful doing that.
Unfortunately, trying to play it from the download is basically impossible without spinning up a webserver due to CORS, so it's hard to work around the issue without a lot of technical know-how.
EDIT: If you do want to try this game, here are some instructions from Mozilla on how you can quickly start up a local webserver: https://developer.mozilla.org/en-US/docs/Learn/Common_questions/set_up_a_local_t...
As for feedback on the game itself, I have no clue what I'm doing. I select 3 dice, it deselects them, and my score is either 1 or 0. It's not clear to me what's happening.
