"Can you handle with tension?"

I made this game since I worked for physic institute but it was the past.
This game is quite complicated and hard, so read instructions carefully.

You are the chef-worker to manage 3 lifters.
Your duty is setting speed controlers and hit the machine to lift cargoes.
It depends on weights.
For light cargo, you may lift it by fastest speed unless heavy cargo, you must lift it slower.
The cable will be ripped off if it pull the heavy cargo by over speed. (For physic students, you know that well)

To reach the next level, you have to empty all cargo in a warehouse.
But you have to be hurry, there are only 120 seconds to complete and the new cargo will always be transfered to your warehouse.
The game will be over if the time is over or your warehouse is over the limit (5000 kg.)

: Controllers :

Z or 4 --- decrease speed
A or 7 --- increase speed

X or 5 --- decrease speed
S or 8 --- increase speed
. or 2 --- lift the cargo

Tips :
You can use the max speed for a cargo under 40 kg.
While the machine is liftting, you can set a new speed for the next cargo.
