This is Korean typing practice game.

Many frequently used Korean words are coming down from the sky like rain drops.
You need to type the words before they reach to the sea level.
If any of words is touching the sea level or the tower, your tower will be polluted.
If the tower becomes too much polluted, the game would be over.

There are special "virus" words.
If you clear them, you can have either of good effect or bad effect on game.

The higher the game level, the faster speed of word drop.

I hope you enjoy this game :)
