Overview: A world divided into eight terrains, each with a rune that maintains and manages the terrain and guardian spirits that protect it. The terrains are destroyed by the contamination of the runes, and the spirits and creatures that inhabit them, including the guardians, are turned evil by the runes.
G, a wanderer who protects the runes of this world, senses that the world is becoming strange and realizes that the runes are becoming corrupted, so he sets out on a journey to each terrain to purify the corrupted runes and guardians!

Design: Design inspiration from the art style of classic arcade games from the 90s, Ussistant aim to encapsulate a stylized and cartoony aesthetic that evokes a sense of retro nostalgia. With vibrant action and effects, our goal is to emphasize the impact and thrill of rhythm gaming.
