Era's Adventures 3D is a beautiful 3D exploration/puzzle game by andev Ltd. You play as a green dinosaur named Yoshi Era; he she has been trapped and must find treasure chests in order to get out.

I have only played the demo so far (full version is $1.99), but it looks kinda .

Apparently, Era's resemblance to the other green dinosaur was coincidental. The developer didn't know Nintendo owned Yoshi (who was what the model the developer used was based on).
