Brilliant!
This was a fun platform type game in itself but what made it amazing was the atmosphere (the music is perfect) and the unique story. I actually felt compelled to replay the game two more times just to see the alternative endings so I could know what happened!
Two minor improvements: 1) I think you should build a check system so that the user can see which ending(s) he has already completed and 2) once the user has completed the game, it should restart to the Administrative level *not* back to the very beginning. The game is short but it was still somewhat tedious to have to redo everything just to see the alternative endings.
Otherwise, though, it was a brilliant game! Keep up the good work!
