This was pretty neat! Kudos to your graphic designer, voice actors, and whoever came up with (or made) the sick tunes. The mini boss battle, though brief, was also very fun!
My main criticism is that it seems like there should have been multiple endings - given that you could finish the game by not accepting your death (and thus defeating the boss) or by accepting death. The same dialogue is used for both endings, though the game design seemed like there was supposed to be an emphasis on the positive outcome of accepting pending death. Since the ending was the same regardless, I wonder why there were two 'choices' at all.
Other than that, I think it would have been beneficial to have some sort of ambience in the initial scenes of dialogue - maybe the electrical hum of the large machine pictured left, or beeping noises from the computer!
