0.99 same as the free?

Ok folks, someone needs to help me here. My son and I enjoy playing stick,an and we went back to play some early games. We added the free version which was very short and then decided to do the longer pro adventure. We paid our $.99 and opened the app, ready for more stick man fun but as far as I can tell its the exact same app as the free version. This seems like a fraud to me. Care to explain?
