Rainbow Yggdrasil

Rainbow Yggdrasil is a turn-based roguelike in which you control a girl exploring auto-generated dungeons in a white world. At its center stands the iridescent world tree Rainbow Yggdrasil. The girl has no memory of what came before she woke in the white world, and sets out toward the tree to learn about the world and herself. Scenario mode tells this story across 30 dungeons and offers over 10 hours of play.

Color and combat

Color is a central game parameter: the girl, monsters, equipment and dungeon floors all have RGB values. The girl's RGB affects her attack and defence, while the colors of her, her equipment and her opponents affect damage. Colors also interact in a relationship where red is strong against green, so you need to consider them when exploring and fighting.

The girl has HP as well as RGB; when her HP reaches zero, the game ends. Picking up an Emotion Seed changes her RGB and her color. Each dungeon floor has its own color, and the monsters' colors vary with it.

Equipment and skills

You find Soulspheres in dungeons and equip them to the girl. Each has RGB parameters that affect attack and defence in combination with her color. Collecting Soulspheres of the same type lets you enhance them, with their RGB parameters increasing according to the colors of the material Soulspheres used.

Memorybits let the girl use special moves. Their effects include area attacks and attack boosts, and their RGB parameters affect skill power. You can replace their skill icons with images of your choice to create your own skill sets.

Dungeons and competition

Alongside the 30 dungeons in Scenario mode, the game has auto-generated dungeons that form an effectively endless labyrinth. You can enhance and synthesize items, and compete with players around the world for clear turns.
