Hello! Thank you very much for your feedback, I really appreciate it. There is indeed a 5-minute timer, but it isn’t displayed to stay true to the theme. The man announces the time right at the beginning (in the first text after the language selection). If you wish, you can try leaving the game running without finishing it—the ending will trigger automatically.
However, I will keep your suggestions in mind for the future. Thank you again, your feedback couldn’t have made me happier.
