Dear Inheritor, our game is an ARPG type, the stages are diorama-style, not open world. About the story part, we have been working hard to expand and enrich it. Maybe you can click on Soul Core - Develop - Memory on the main interface. Learn about the background stories of the bosses to get a better experience. About bugs, we will always work hard to optimize the game experience on various phone models during the testing period. If you encounter any bug, please feedback to us with detailed screenshots and descriptions, this will help us make the game better.
