I expect that these things would tend to appeal to alterhumans. The things in this collection aren't about alterhumans. (Or, in some cases, aren't necessarily about alterhumans.) For example, plural systems like character customization tools to create pictures of their headmates. Therianthropes tend to like simulation games about bird flight and other animal behavior.
For brevity, I'm using alterhuman as an umbrella term that can potentially include as many members of these groups and identities as personally feel they relate to what's in here: therianthropes, otherkin, fictionfolk, plural systems, and furry lifestylers. On my profile, I have other collections of things on itch.io that are actually about alterhumans, with explanations of what they are.

Relevance: I think therianthropes would be interested in this.

Duration: A few minutes long. One play through to see all.
About: Non-fiction. A trans woman's personal memoir where she explains what she means when she says she is a pupper. It's a reference to a meme that felt really meaningful and helpful to her.

Medium: A tabletop role-playing game (TTRPG).
Story: You play as a daemon disguised as an animal-folk to experience things in their world.
Relevance: I think otherkin would be interested in this because it's about a nonhuman protagonist trying to fit into a society of a different species than their own.
Content: Rated PG-13. References to bodies and sex aren't explicit.
Medium: A supplement for any tabletop role-playing game (TTRPG) or story that has nonhuman cultures.
About: In a nonhuman culture, would they have the same norms about gender and relationships? What do they think makes a gender, could it be something else unrelated to what humans think is key to that? Consider these questions when you're world-building or designing a character. You can use these dice rolling tables to generate some ideas for your game or story.
Relevance: I think otherkin and xenogender people would be interested in this because it's about experiences of gender that differ from human norms.
Content: Rated PG-13. Consensual physical intimacy and desire.
Medium: An interactive fiction story created in Twine.
Duration: Each play through is a few minutes long. Replay with different choices to see each of the story paths.

Relevance: I think otherkin would be interested in this.

About the author's experiences with being autistic and transgender, and how this relates to domestication and wildness.
Relevance: I think therianthropes would be interested in this because it contextualizes personal experiences in animality.
Content: Rated G. Friendly for all ages.
Medium: Live Action Role Play (LARP).
About: The players sit in a circle and use nonverbal communication to role-play as wolves in scenarios described by the game master.

Content: Unrated. I haven't tried it yet, so explore with caution.
Medium: A solo journaling tabletop roleplaying game (TTRPG).
About: You play a changeling as their loved ones find out that they are secretly a fairy. It's meant to be about autism, ableism, and the pain of pretending to be neurotypical.
Relevance: I think otherkin would be interested in this because it's about a nonhuman protagonist trying to fit into human society.
Content: Rated G. Friendly for all ages, though it deals with some topics that are heavy or that some may find troubling. Hunting and fishing for food. Your character can black out from exhaustion, or get thrown in jail. However, you don't die, and you don't do combat. Some story elements are about hunger, poverty, homelessness, the displacement of Native Americans, and the enslavement of African Americans in this game that is set during a period of US history soon before the Civil War.
Accessibility: Closed captions for audio dialog. Some text on screen is in cursive and doesn't have audio narration.
Medium: A first-person video game, sometimes called a walking simulator.
Story: You play as Thoreau in a historical reenactment of his memoir Walden. It's very detailed and accurate, aside from where it has to take artistic license for game play reasons.

Content: Rated G? I haven't played this yet.

Story: A visual novel of romance and murder mystery set in a world of dragons.
Relevance: Though you can only play as a human in this game, I think dragon kin would be interested in this. In fact, many of the backers of this game's development were members of the dragon community. One of whom, a dragon otherkin, Goldkin, backed the game at the highest level, inserting a couple of their own fictional characters into the game, Lorem and Ipsum.
Content: Rated PG-13. Photosensitivity warning for flashing lights! Warning for description or depiction of panic attacks, social anxiety, unwanted intrusive thoughts, depression, low self esteem, suicidal ideation, dismemberment, painful experiences, protagonist death, family member death, violence involving animal-like fantasy creatures, and sexual violence.
Accessibility: Again, photosensitivity warning for flashing lights! You play with a mouse, and some puzzles require you to click on small details extremely fast before a short timer is up.
Medium: A computer game that was created in Flash. A visual novel with occasional puzzles you must solve to progress.
Duration: Hours. It's impressive that nearly all of the music, interactivity, animations, and hand-drawn art were created by one person, especially given how long and fully-realized this game is. Make sure you unlock all the endings to get the whole story, because the final secret ending is important. If you get stuck on that one, it's worth looking up a hint from other players to get it.
Story: Unconventional fantasy. An adventure through a world where people's thoughts can manifest as nonhuman entities called thoughtforms or tulpas, who are sentient personifications of ideas, and people can train to become something like magicians who use their own thoughts to influence their surroundings.
Relevance: I think plurals would be interested in this because of some of the world-building about thoughtforms and powerful thoughts.
Content: Rated G. Voluntary transformation. Cooking food.
Medium: Computer game. Play with a keyboard and mouse (WASD controls), or a video game controller.
Story: A peaceful, wholesome, somewhat surreal fantasy game about running a cat café on a magical island where your neighbors are witches and people can turn into animals.
Relevance: I think therianthropes, otherkin, and transspecies people would be interested in this because of its voluntary transformation themes. You play a human protagonist with a lot of unlock-able character customization options, and you can find a spell that you can optionally use to turn you into a cat.
Content: Rated G. Friendly for all ages.
Medium: Brief instructions for a single-player live action role-play game (LARP).
Duration: You play it for a couple of minutes occasionally during your day.
Story: As a mindfulness exercise, you try to pretend that you are explaining to an imaginary friend about the real world around you.
Relevance: I think friends of plurals would be interested in this.
Content: Unrated. I haven't tried this yet, so explore with caution.
Medium: Computer game.
Story: An educational computer game that simulates living as a wolf to teach about their behavior and their role in the environment.
Relevance: I think therianthropes would be interested in this because you play as a realistic wild animal.
