I added this one to the list some time ago. It's sort of a cross between Elevator Action and Venture. I'll have to make sure I find time to see if it's still as fun as I remember.
This list of items off Klov should come in pretty useful for playing the game though...
You must find several items by searching each room on floors one through four. The items you will need are:
An umbrella - required to allow you to escape from the top of the building.
A key - needed to open the locked door on the fifth floor.
A tool - used to break the elevator so that the guards will not be able to exit the building and capture you when you escape.
An ID card - turns off the electric floor in front of the safe.
A disguise - needed to get past the guard in the fifth floor room.
A map - helps you find your way.
A safe combination - needed to open the safe containing the secret plans.
High-speed jet boots - lets you run faster so you can avoid the guards.
