The Locrian
About
An interactive short-story about our relationship with the future.
If you want more stories from this universe, you can go play Somnia, which acts as a kind of prequel to this one even though it was written first. You can play it here.
And yes, for you music nerds out there, both the title track and a certain character's piano theme are both written in the Locrian mode.
Note: The downloadable version of the game has a save system, the web version does not.
