Industrial Disaster

You are a simple worker in a bio-chem lab and have worked here only a couple of months. Then one day,
an accident occur, and all the staff hastily evacuates.
But you were left behind, and must deal with a seemingly invincible monster.
And soon there will be a chemical explosion, and if you do not get out
in time, game over! You will not only have to execute
a helicopter landing, but also solve several puzzles to get
keys to open different doors. In your arsenal are only your legs and head,
so do not waste time, just act, because time cannot be stopped either....
