Multiple problems...
I had multiple problems with this movie. Not technical, just overall.
The music was good, but ultimately repetitive, and belongs in an 8-bit game, not in a submission such as this.
One of the problems with the overall design of this was that everything had to be in a pixellated format. An original idea, but poorly implemented. It seemed as if no one knew whether it was 8-bit, 16-bit or 32-bit.
Another problem was that although the theme of this was pixels, it seemed as if many artists simply made their submission, and used an automated tool to convert it to pixels, which looks fake and tackey.
So there. 4/5.
