Basically, its going to be a multiplayer sequel of my game: The Cube is Everything(not released yet).
The Cube is Everything game is about a cube that can do anything. Something like Scribblenauts, but uses verbs, not nouns. If you type any action, the cube will execute it. You use the cube to solve puzzles.
For instance, you type in "hover". The cube will hover.
Or type "make fire". The cube will start a fire.
Or type "timetravel" and so on, an on.
Translating it to multiplayer:
-Each player gets one cube each, and the players must kill the each other's cube or the player character that controls the cube.(The cube is somewhat independent of the player).
-Sleep is Death type game where one player controls the cube and another player manipulates the environment.
-Instead of CTF, Capture the Cube! The players engage in a deathmatch and capturing the cube lets you manipulate it for a short while. Then it disappears.
