I mean, it was pretty nice, but you should add something else instead of 'hide and seek', you know? If i was you, i would change the game to something else AND try to make it creepy that way! For example, i would make the MC's Creepy doll play jump-rope with it. It would be like this: there would be spikes moving towards you, and you would have to play jumprope to avoid it. But the spikes would move faster and faster each time you avoid one, and you would slowly have your feet impaled and die of blood loss, and then the doll would posses your body and that way you would be 'it'! But still, i think this was a nice story, it just need to be a teeny bit more polished!
my idea was there are children out there who were murdered then someone made a doll of them and they would posess it. The child plays with another child who has said doll and must win them in a game say hide and seek. Once they are caught they die and their death is left a mystery and they turn to a doll as well making the "it" and they need to win another child in a game to escape the doll and possess the childs body giving them the ability to live a normal life. I also have a bunch of other stuff which wasn't needed in the story but it's something. Anyway this little girl died as well in hide and seek with a doll back in 1912 and this girl who dies in the story was the person who has the doll of her meaning she's trying to win a game. At the end the 18 year old we follow the story of is dead and has gone into doll form. The cycle continues and such. I really think the only problem is I need to make it more eerie. But now I realise I need to make my point clearer as well judging by the fact that you did not get what was happening.
