Said features include a timed mode where burning red letters destroy the tiles below it before hitting the bottom and resulting in game over. There's a library which stores words from certain categories, which you can refer back to in order to complete the set. And there are special bonus words that crop up in the top corner that give you a massive bonus if you spell them.
