Thank you for your detailed comment.
There is indeed no sound in the game, but that is only for now. In the near future I plan to add everything.
My game is at the very beginning of development. The main character does indeed give that impression at first; as the game progresses, he is supposed to learn, face difficulties, deal with manipulation from girls, and become a true Academy Master.
Short biographies of the girls are also planned; at the start of the game I plan to gradually reveal each character.
Thank you for your comment.
