I've played as aliens, space ships and astronauts in plenty of games before. But a wormhole? Now that's novel.
If you have 15 minutes to spare, I highly recommend giving You Are A Wormhole by Aleks Sennwald a try -- it's a charming little game about being lonely. Every so often, an entity will reach your corner of space and you can choose how to interact with it (or not). The results are unexpected (you are a worm hole, after all), funny, and kind of sad.
What results did you get? Apparently, I'm a bold worm hole. I'm chalking that up to interacting with nearly everything, and at one point being somewhat of a dick to a space ship. Whoops.
