Folx, I'd like to share an example of a gamezine. Some time ago I created a game called Cydonia. I made it intuitive, just based on paragraphs, because I didn't want to add statuses or anything that would mitigate luck, apart from the choices themselves. I'll leave the link here for you to see.

Also some time ago I created a pamphlet called What Hides in the Dark, it's not in zine format, but with the exception of the map and a reduction in the rules, it would also fit in the Jam format, I'll leave it here in case you're curious.

I hope it helps and serves as inspiration. I'm looking forward to taking part in this Jam with you, this time I'm going to try something slightly more complex. Good luck and lots of creativity to you!
