It goes without saying that the presentation is top notch. Love the look and sound of the game. The idea is very creative; having the ability to resize both the "character" as well as the environment is very fun.
I think most problems with the gameplay can be ironed out by giving the player more time to react. As there is barely any, we are forced to rely on trial and error or follow the prompts on screen. I fear the mechanics weren't given enough room to breathe. If you zoom out the camera, and place the dinosaur at the very back, you would give the player more room to venture forward and re-size the environment in preparation. This may also increase the challenge by creating more distance between the scientist and the dinosaurs.
