Pretty promising
I really enjoyed the sexual tension that exists between the two shapes... it really builds for a great climax at the end. I think the fact that you went out of your way to channel that relationship between these two men is spectacular. I particularly like that you've managed to simplify the characters and animation to the point where the user can truly isolate him/herself with the pure emotion of the piece as opposed to Adam-Phillipsesque bells and whistles. I think thats pretty damn spectacular and bold.
My only reason i didnt give a 10 is because i felt like a cameo appearance by a triangle or hexagon would have been a nice touch and added an air of mystery and mystique to the piece.
