Sucks you in but leaves you disappointed in the end.
Overclocked itself is not so much a game, but more a interactive movie. Often you go from cut scene to cut scene. Even if you can do something in a flashback, then it is very linear and easy. When you are controlling David mostly your task is to play taped recollections to patients to trigger more flashbacks. There definitely aren't any puzzles in this game.
The story tries to do much more than it ends up to be. It contains many standard expected elements seen usually in films like the main character having personal problems, much of the game taking place in desolate buildings, the constant stormy weather etc. The ending turned out to be very disappointing and left many things still unsolved like why the patients needed to escape anyway. The story seems rushed and simplified towards the ending leaving it unbelievable.
One of the most annoying aspects is that when you want to skip some text, it is not possible as you can only skip entire conversations and cut scenes. The game crashes occasionally when loading a new scene, so it is necessary to remember to save often.
The graphics are comparable to most other adventure games. It is the small number of animations that is annoying. When controlling the character, he seems only capable of walking and running, for all most other activities the screen goes black and the activity is done then. Also in cut scenes the characters' faces hardly show any emotions.
The voice acting is not that bad, but often muffled by the repetitive music. The dialogs are mostly believable, but the faces showing no emotions make them at times ridiculous.
The main frustration with this game is that you suffer through the poor game play to find out what happened to the patients only to arrive at an unsatisfying and unbelievable ending.
All in all there much better games to spend your time on. This one offers no challenges and a disappointing story.
