Only Herbert(Yellow) can drive the elevator

The story:
Herbert (yellow) is a physicist who risked his life inside a particle accelerator to create a mini Black Hole, but things didn't go as planned, causing a major disturbance in Space Time where the present joined with the future.
Mark (orange / red) from the future will help Herbert escape the lab, But it's not just Mark who came through the Black Hole ... (find out by playing)

Herbert is able to see only the present and what mingled in it, Mark can see the scene from a future perspective, so he can "go through some doors and walls" as they do not exist for him.
