Gurumin is a 3D platform game with heavy emphasis on action through
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 are 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 purchase (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
