Spirits journey of the dead (Tentative)

So game concept. 

You are basically following the journey of two spirits, connected with each other by one protector/ guiding spirit. One spirit is a young girl who had recently passed away, and is now a reaper in training. The other is a young boy, an angel devoted to keep the spirit realm and physical realm at balance.

Spirit realm is an area split into three sections. paradise where the souls of the good go to, damnation where the souls of the wicked go to, and the wilds (tentative) where all other spirits are. 

Physical realm is the realm of the living. 

Spirits from the wilds (tentative) can cross the bridge into the physical world. 

Your task is to help them keep the realms at balanced. But be careful, they are only kids.
