We understand there may have been an issue with the home screen. The game should now be fully playable. We also hope the tutorial functions correctly for first-time users. Im are actively developing a solution for mobile users to access the tutorial. PC players can currently press the enter key to reopen the tutorial at any time. This feature ensures all players have the ability to review the instructional content as needed. I aim to provide a seamless experience across all platforms. A "book" button is now available, which will provide information about the abilities of each suit. This addition is designed to offer a clearer understanding of the game's mechanics. We hope this will contribute to your enjoyment and strategic depth.  Your engagement with our platform is greatly appreciated. We are continuously working to improve the user experience.
