One of the most original game ideas I have seen for some time. The scenario is for you, a secret agent, to get to the top of a building to solve the case. Simple enough, until you see the killer elevators (OK, lifts to you and me!) whose shafts you have to cross to ascend each level. If the lift cage touches you in any way you are squashed.
This means there are elements of planning, speed, skill and dexterity. Survival is not simple.
Graphics are good and have enough speed to make the game interesting. There could have been more colour - the screen is too bright. Control, via joysticks, is fairly precise but it is possible to make mistakes accidentally. Movement gets more difficult the higher you climb due to the lessening room and time for manoeuvre.
There is little in the form of extra diversions. I could have imagined invisible lifts or safe ones flashing for short periods and, most galling of all, you are not allowed to get into one for a ride.
