Weird but Awesome
The best part about this flash is that it doesn't have a point (something that all flashes usually have). Although it can be understanded and interpreted with specific knowledge of the ocean (the abyss, twilight zone, and such) the fact that it doesn't make much sense doesn't take away from the quality.
The music is synced in with the flash perfectly, the graphics are great, and once you see the colorful fish swimming above the abyss, you can have your own thoughts on what's going on. Unlike most flashes, this lets you think, while making enough sense on its own.
I really have no problems with this flash. The transitions from the bleak, slow world of the abyss to the colorful, bright world above fit right where they are supposed to. The graphics are extremely high quality, the music is in sync, and the concept of it is vague (a good thing). 10 out of 10, 5 out of 5.
