During the ongoing trial between Epic Games and Apple, the latter company accused Epic Games of allowing "unspeakable" titles on its store because it supports Itch.io, an indie game platform where anyone can publish their work.

With more than 60 developers already signed up, The Unspeakable Jam is open for submissions until June 12 because, in the words of its organizer, "That's as long as this joke will be funny." In addition to making games that presumably contain some degree of adult content, participants' games must have a beginning and end with challenges in between.

This is another jab at Apple, who used very rigid definitions for "games" during the trial.

The "unspeakable" tag on Itch.io currently only has 42 games, and most of these don't contain anything as morally despicable as Apple implied
