Hello everyone! This update mainly focuses on improving the beginner tutorial. The main menu now includes a clearer step-by-step guide to help new players understand the basic flow of 17 Steps, including tile selection, battle, the Dark Area, and the scoring phase. Image sections have also been added to the tutorial to make the rules and controls easier to understand. In addition, this update improves the AI algorithm for tile selection and discarding. It also fixes an issue where the AI’s starting hand could sometimes fail to be in tenpai. The AI should now behave more consistently and follow the game rules more reliably. Thank you very much to everyone who has purchased and supported 17 Steps so far. As a solo-developed indie game that is still being improved, your feedback, playtime, and support mean a lot to me. I will continue improving the game based on player experience, fixing issues, and gradually adding more refinements. Thank you for your support!
