Tetrabomber

This is a 4-player party game, so you'll need at least two game controllers and a few friends to play.

The basic premise is that each player occupies their own "world" (playing grid), and each world is connected to another player's. When you set off an attack in your world, the attack materializes in the connected player's world. Likewise, some player will be connected to you, so their attacks will materialize in your own world.

As you play the game, events happen that change the way the worlds are interconnected, and add new objects that are synced across the worlds. There's a good amount of visual multitasking that needs to go on to be able to survive both on the offensive and the defensive.

Due to some schedule conflicts, I only had one day to work on this, and in that time I didn't get a chance to actually test out the game with anyone. So, I honestly have no idea if this idea works in execution... if anyone plays this with their friends, and can record a video of it, I'd love to see it.
