CIMA: The Enemy

CIMA: The Enemy, known in Japan as Frontier Stories (フロンティア ストーリーズ), is a role-playing game developed by Neverland for the Game Boy Advance. It was published by in Japan by Marvelous Entertainment and in North America by Natsume. It follows the story of Ark and Ivy, two aspiring Gate Guardians. It is their duty to protect the innocent from being captured by the CIMA, an alien race that feeds on human hope.

In CIMA, you must take a number of NPC characters, each with their own special abilities, out of the dungeons the CIMA have created to feed on human hope. CIMA build their dungeons on this principle: without an escape, Humans lose hope. Therefore, they take their time to appear not as powerful as they could.

The game starts off with Gate Guardians Ark and Ivy in a train en route to the frontier: a land where people can start their life anew. However, CIMA attack and suck the train into one of their worlds so they can feed on the humans. The game relies on an interesting combat system where you must direct fourteen party members to different switches, almost like a planar version of Lemmings.
