Overture is a nice game... until you reach Act 3 of the first Zone. You run towards the act and something keeps poping up and you eyes gaze with wonder at those marvelous yellow blocks on the walls. You totally can reach those they're just a jump away... where could they lead? What magic and wonders would you uncover climbing through those marvelous and ridiculosly shinning yellow blocks?... and then you jump and... you go through them, because they are not solid and you want to cry because of that. All the mystery is gone... life has no meaning.
