RekcahDam (who contributed the music for They Do Not Die and Dance Clone and perhaps more famously worked on Wings of Apocalypse and rComplex) recently released a new PC game titled Stream.
Stream is a experimental game project some friends and I have been working on. It sports a some side scrolling shooter elements but the main theme of Stream is time travel. You play as a guerilla soldier who wont stop until he completes his mission.
But just remember that even once you complete the game you can never be too safe.
