Lisa is an inventive witch, highly skilled in the art of crafting potions. One day, however, one of her potions goes awry and opens a rift that drops her in another world. This strange world is made up of floating islands inhabited by peaceful gnomes and thieving imps. Only the gnomes know how to get Lisa back home to her own world. But first, she must help them defeat the imps who have been stealing all of their magic potion ingredients. By constructing resource buildings and matching potion ingredients, Lisa can clear the way across the five islands for the gnomes to gather the artifacts that will open the portal home.
