So I woke up and start think about the my game. Here are my thoughts.

1. You are a manager of graveyard in year of 2120, so many people died and get their grave on public graveyards, and you are choosing which grave to destroy and put another guy into it. It is Papers Please game about decisions.

2.Multiplayer 2D arena game where weapons cause decrease of play area.

3.Singleplayer/Coop Multiplayer 2D game about to stay long as possible alive, fighting against AI which is going to decrease playground area.

Time to do something finally
