Kamigotchi World ecosystem has ushered in new developments—community developers have created the Bags application for it. The emergence of such derivative tools reflects the activity level of the project's ecosystem construction and also signifies an increasing developer participation around the project. Whether a Web3 project can sustain long-term development largely depends on the richness of its ecosystem tools and the community's innovation capabilities.
