The worm flies through the sky dropping words. When they land click on the words to hear them and make them disappear. (You can't make them disappear until they land.) Perhaps the player should try to read the words before clicking on them!
You can make the words (on average) easier or harder by changing the level. This can be done when a game is in progress or when it is paused/finished.
You can make the worm drop words faster or slower by changing the speed. This can be done when a game is in progress or when it is paused/finished.
