 Both Lex and his enemy have health meters (represented by a number of hearts) which, when depleted, signal defeat.However, unlike more traditional role-playing games where players can injure their opponents with arms or magic, enemies in "Bookworm Adventures" are damaged by forming words.As in the original "Bookworm", words are formed from a grid of available letters, although unlike the original, the letters used to form the words need not be adjacent to one another.
