Sutte Hakkun

Sutte Hakkun falls into the category of a side-scrolling, level-based action puzzle game; a genre best represented by the Lode Runner series. The player controls Hakkun, and attempts to gather up the rainbow shards distributed across each level. A level is completed when the player finds all of the shards hidden in the level. Levels are arranged simplistically at the start of the game, but become highly complex and difficult near the end. The final goal is to find all of the shards hidden in the game.
