How can this achieve a better score?
It had no point, no sound or any animation (really) involved. It wasnt a cartoon, it was just cubes appearing on the screen, one after the other.
A good start would be making it more enjoyable to watch because no one would really find this entertaining. Adding colours, things that move etc etc...
There could of been music, too. Not good by any means but you should think about submitting something that people want to watch on NG. 0/10.
