Game Running Very Slow

[slash23]

I just started playing this game and I really like it, but for some reason it is running very slowly on my phone. I've seen videos of other people playing this game on their android phones and it runs extremely smoothly, but mine is slow and choppy. Does anyone know why this is or how to fix it? I am using a "LG Optimus V Android Phone" if that helps.

Here is an example of how the game should look: http://www.youtube.com/watch?v=SpaM9...eature=related

But mine is extremely slow and choppy.
