You know it, you are going shopping and you cannot find the things you want. Here the time limit is really killer but luckily all the things you have to find are put logically. But it's not always so. You can find Pepsi near a cat sitting on a shelf. If you click on a wrong object you lose some time. There is small glitch, when the time limit is under 20 seconds you cannot lose any time by mistakes, so use it.
