Ancient legends speak of a golden age, when music tudidumtudidumed and vast legions of tetrominos dropped from the heavens. 

They fell, and spun, and fell and spun. Left, right, right, left, down. All the directions they traveled!

Except up. There never was an up.

But those days are long gone my child, and all that's left of these majestic shapes are bits and pieces, buried deep beneath the earth.

They are rumored to bestow great powers upon those brave enough to venture down into the darkness to retrieve them. 

But beware young one! There be monsters...

Venture down into the abandoned Tetris mines and use your boom boom sticks to dig out the ancient tetrominos of Game Boy past. 

Try not to get killed. 

You're allowed to cry, if you must.
