So, everytime you put in a number the game uses some functions to determine what the game with be like. In some ids you will find a person with long hair, if you touch this person, the game finally concludes. The number works almost like a minecraft seed, where you know the same thing will happen everytime you use it, but you have no idea what it is before.
Had another go at this; thanks for explaining to me how it works. But I didn't find that the play experience worked very well--you're doing the same very small loop over and over: Walk up the stairs, walk over to the other room, either your mom is there or she's not, start over. And there are some different props and things, but you're not making progress--you're just trying to guess a random number.
