Does temple run work on 512MB RAM WP8 devices?

I was thinking of buying a Lumia 720 but I heard that temple run does not support 512MB RAM devices.Is it true? I saw a pic on Nokia's FB page which sowed temple run on a Lumia 520.But it has only 512 MB RAM.

How many WP apps are there othere than this that dont run on 512 MB RAM?

link to the pic.
