You've just been accepted to university on Earth; you say farewell to your family and start your comfortable, luxurious trip through space. Once you're on your way, though, you realize you might not be alone.
Stowaway is a Twine story from Tanya Short about something that doesn't belong—the idea of an intruder, the idea of the self. It's very graceful and restrained, immersing you as much in the chill of its spaceward journey as in memory and emotion. I think the writing is fantastic and the storytelling dreamlike; calling it a horror story is my choice—you might get something different out of it.
Stowaway is free to play here. I've worked with Tanya and her studio Kitfox Games previously through my game design consultancy Agency, but that project wasn't related to this one.
