Here we have two roles for player:

or

In A 2d Board World

2-8 Player Online Competing

There are three game modes in Witch and Spirit:

Casual

Players who play as spirit are going to hide themselves in the mystery land until the end or breakthrough the world in a special way.
Players who play as witches are going to find out where spirits are hiding.
In this mode, spirits are encouraged to collaborate with other spirits. As long as there is still one spirit hide till the end. Spirits are the winner, or the witches are.

Pk

Spirits and Witches are going to collaborate together if they are on the same team, and different teams will compete with each other by catching all the other spirits.

Connect

This can be treated as a hard mode of Casual mode. In this mode, all the spirits share their stamina and energy which makes the game difficult. As long as one spirit gets caught by the witches, the game is over.
