When you think of genres with standout authors, "mouse train" may not be one that immediately comes to mind, but perhaps that's a sign that you should try more solipsistgames.
The Neo-Twiny Jam is a long-running game jam that looks for games using 500 words or less. Sometimes that helps encourage new or busy authors by giving an easier target. Other times, it encourages creativity and fun, seeing how much game you can fit into those constraints. (both can be true of course)
This game takes the 2nd path. It's brief, and has a simple premise: a mouse takes a long train ride, and other creatures join the train, whom you can try to talk to or not.
There is some tension from people's reactions, which feel pretty realistic to me. And there are a couple of different endings.
What I like is the truly lovely art for the game, especially of the creepy critters. The game itself is only a couple of minutes long, so I definitely encourage people to check it out!
