There was a surprising amount of backstory to be found. I really like the fact that it's more or less optional and you can skip it if you want. I don't see why anyone would, as the game is well written. Took the time to play both (and a half) endings. Well worth the time. Endings 2a and 2b (so to speak) were the same for me (the Doctor) though.
The pixel graphics are absolutely up my alley. They look terrific and fit the mood you create nicely.
Fantastic game.
