The objective to any level is often simple-- retrieve a star. It's the path to that star that generates the challenge and thrill of the title. There may be tripwires, killer sharks, or simple environmental obstacles like a tree blocking the path. To overcome them, the gamer just thinks of anything-- and so far, that really is anything-- that may assist getting the hero, Maxwell, to the star. Via writing on the touch screen, or tapping letters on a touchscreen keyboard, any item, monster, animal or person can be summoned, and a "did you mean?" spellchecker will pop up in case you're not the world's best speller.
