You have the old version with episode 4. We are currently on episode 6, and next week there will be episode 7. The Steam release has been moved to March 14 and will include the endings.
Awesome game, different and interesting so far. I will definitely purchase a Steam version, though not a fan of doing it twice. I guess I will wait for 1.0 to drop here, if you're certain that will have the Steam key.
