Release Announcement and Bug Notice
The game is scheduled to launch in about two hours at midnight on May 13th, Korean Standard Time. The release button has not yet been activated, causing a delay in the launch. The game is expected to be released within today, May 13th. Thank you for your great interest. Currently, there are issues with data resetting, as some information is not deleted when either directly removing the game from your Steam library or deleting data files from the local folder. Please be cautious when attempting to reset the game. In upcoming updates, we plan to prioritize the creation of a feature to delete all data in the 'Settings' menu. Additionally, following a data reset, it is anticipated that the in-game scripts may be affected, and as a result, the game will be programmed to force quit.Read full article on Community Announcements (E.Clone)AnnouncementsOfficial
