Well I have reached a milestone I suppose, my son is now two and with this we move on to apps he now loves being < 3 years old. You can see my previous reviews here:

First off let me say this: every single Genera Interactive book / game etc is work downloading, these guys are spot on in their interactions, design, and stories. 

What makes Marina and the Little Green Boy so entertaining for my son is all of the interaction the bilingual story contains; almost each and every element/character that appears on the screen is able to be tapped, to create funny sound effects and animations. My son just loves the little Martian laugh: "naaaanuuuu naaaanuuuuu". The story itself is in-depth and not just an add-on to the interaction (which we sometimes see), so there are plenty of screens to be enjoyed.

For $1.99 it worth it and as I said before all the Genera iPad apps are worth it for their creativity.
