Any way you think about it, Tetrisphere is weird. You're playing Tetris on a sphere (duh) with some bizarre little robots.
But what would happen if, say, you went to start a new profile and named it 'vortex' (without quotes, obviously)
You'd hear a sound like you did something, but nothing would happen. Odd.
If you push and hold down the Reset button on your console, however...
A black hole appears and sucks the game's characters into the void! And it'll keep on repeating as long as you hold down the Reset button.
