Please protect me (to be able to taste the thrill)

Details

In this game you save as many red man as you can, just in the nick of time. They want a thrill so make sure it's at the very last second. They hate pain. It's a power game. You decide the speed of the black sphere. If you press the brakes then you will stop the black sphere. However, you cannot stop the black sphere suddenly. You need to be aware of your timing. The other men along the way are inconsequential. If they're hit then they will slow down the black sphere. You're bound to hit them along the way so it's a challenge at the speed you anticipated for them. If you're good and can stop it just in the nick of time then everyone will be so happy. But you will sacrifice a lot of other men along the way. They will become a sacrifice for the happiness of one person.
