Multiplayer
There will be a bunch of different Multiplayer modes:
Turn based combat is disabled in multiplayer mode. Pausing is also disabled in multiplayer mode.
An in game chat system will also be needed.
Competitive
This will be mostly a mini game, where one player can take the role of a monster and hunt down the other player.
Guidance
A player can invite another player into their game, and have them help guide them. The joining player will take on the role of the familiar and can show the other player paths or secrets.
Co-op Mode
This will be the main multiplayer mode. After the hosting player unlocks multiple magical girls, they can invite other players to join them on missions and playing the story campaign with them.
Anti-Grief
Only friends can be invited to the game.
A public/private key will be generated. The public key can be exchanged through outside means.
Client Authentication will be used to ensure that the person joining is who the host wants to join in.
