Gurumin

Gurumin: A Monstrous Adventure (ぐるみん) is a 2004 action role-playing game developed by Nihon Falcom. It was originally released in Japan in December 2004 for Windows. A PlayStation Portable version was later released in Japan in June 2006, then in 2007 in North America by Mastiff in February and in Europe by 505 Game Street in March.

Gameplay
Gurumin is a 3D action RPG with heavy emphasis on action through real-time combat. Parin can acquire various headwear which have varying effects while equipped, such as protection from water damage, stronger attacks, or HP restoration. Each piece of headwear can be upgraded to increase their effects. Parin's drill has up to four power levels that are increased through combat or restoration points in levels and decreased by taking damage. The current level of her drill dictates damage that can be dealt and can change up and down frequently in each level. Various consumable items can be bought or found which are used during levels to restore HP or drill power.

Gurumin offers replayability by offering new difficulty levels upon completion of the game. The game starts with Beginner and Normal modes; Hard, Happy, and Crazy modes are opened up with completion of the previous difficulty level. While each difficulty alters the strength of the enemies, some also change other elements of the game, such as removing environmental hazards in Beginner mode, an altered game script in Happy mode (Japanese version only), and only allowing damaging of enemies through critical hits in Crazy mode.

In addition to headwear that gives characters various abilities and protection there is also a number of outfits that can be equipped. Matching the right outfit with the right hat could unlock additional abilities. These are acquired by purchasing from the (vending machine), completing the game at a set difficulty level, or through other means, such as playing on the right date when a special event happens.

Plot

To thank Parin, the monster takes her to a crack in the back wall of the town which is revealed to be a portal to the monster world. A group of monsters known as phantoms begin a series of attacks on Monster Village. Parin, who unearths a legendary drill, decides to fight against the phantoms and restore Monster Village.
