The storytelling was my favorite part of this. It was super cute, and it fit the theme well. The pictures in the book and the book itself were really nice, and the models in-game were good.
The gameplay was on the verge of being good, but needed some in-game explanations to improve the experience. Things like the chicken egg knocking over pitchforks and the emu egg exploding were not intuitive to me, and I only figured them out after re-reading back to the web page. I also found the invisible walls to be a bit confusing. I understand they're meant to keep you on track, but for things like the spikes in the emu level, I ended up just walking around the full border looking for a way to escape assuming that the invisible wall had a hole somewhere because the spikes didn't scream "breakable" to me.
I still enjoyed the adventure of becoming a dinosaur though!
