No INTENDED metaphor, but definitely metaphor.
I saw some analogy here that applies to many aspects of life, though you say it wasn't intended, it's definitely there. I can see alot here pertaining to conformity (They had to make horrible sacrifices for a temporary high that fizzles out when they had nothing agreeable left to give), hell even drug usage, but I won't go into all that because I don't feel like typing it. It's definitely quality flash, decent graphic, and an interesting story. I found the pacing to be a little fast, because it was kind of hard to pick up on, especially with there being no narrative, but otherwise a damn fine distraction and a good effort. Keep up the good work man =)
