Celtic Heroes

Hi there, I use an iPod 5th Generation, and when the update for celtic heroes was released it updated on it's own, but I wanted to try the fast graphics just to see how blurry it could be. Now when I try to remove fast graphics, it doesn't allow me saying that it exceeds my device's limit or something. Is there anyway to reverse this?
Thanks!

It's not available in the menu.

When you log your character before entering game you will be taken to character selection when there click on the options, then click graphics settings. From there you should be able to turn of and on fast terrain/ default characters
