Push Things Edit
The Push Things mechanic is used by the girls, Yui and Haru, to get pass all sorts of new puzzles in the second game.
They'll have to push boxes and other possible objects out of the way in order to create a pathway for them to advance.
Other times, they'll have to make use of the boxes to create a bridge for them to advance in higher platforms. So they must push them in the lower platform into that right spot if they want to advance higher up.
Finally, the girls will have to go there classical mazes littered with several boxes. They'll have to figure out which box to push and where to push them in order to get through the maze. If they're not careful, they'll end up trapping themselves or make it impossible for them to advance to the next area.
Be warned that, because they're just little girls, they only have the strength to push the objects. They cannot pull them back, so be careful not to create a irreversible mistake or else you'll have to reset the whole thing.
