There is no goal or any way to win in this game. It's an interractive experience meant to allow age regressors to experience their fantasy of becoming a child again of their desired age.
In this game, you go to a daycare that has a special device that can change your age and allow you to play as a child for a day. You can explore the many rooms of the daycare and talk with various other children and staff.
I am having troubles running scripts correctly so currently, the only age available is 8 years old but I plan on changing tha tin the future if I ever manage to make it work.
