"Old Times / New World" is divided into two chapters:

[Old Times Chapter] The main experience is based on the "nurturing gameplay". Players will take on the role of the protagonist and manage a "game development club" during their college years. Through planning and decision-making, they will complete their ideal indie game.

[New World Chapter] The main experience is a "visual novel". It tells the story of the protagonist group after graduation, entering a game company. There are 5 female leads to be pursued and more than 15 endings. The core content is both a love simulation and a portrayal of the workplace of game people with different identities and positions.
