If you are expecting this to be a "game", you will be let down. This is more of an interactive cinematic adventure. You do not get full-control, youre presented with challenges. Example: The character is running and falls in a video, youre prompted with "swipe screen repeatedly to get up", or the character hears a noise and prompts "tap here to investigate".
The graphics are good on my iPad 2, as good as the screenshots above. There were a couple lags in the videos, but nothing major.
Overall, its an impressive app, but the lack of any control gets boring, youre simply watching a Jurassic Park cartoon.
