Ok, If I had to compare the two, the 2-headed logo at first really drew my eye and I thought it to be a good choice, also since it has a certain playfulness, since it's for a game.... However, something wasn't working for me. Maybe it's the font? It's just not working with the Titles proposed so far.
I still love the originality of the foldisaurus, but it's style is too different from the characters you chose to be in the game. Here too, I haven't seen a convincing combination with the title, though it's better.
I like this one, which combines the two approaches.
My advice, I think you should try to find a way to bring the origami look to the title as well, so that the logo is fully coherent.
