Issumi Yamamoto is a programmer at a game company. He loves games and enjoys programming. However, on the other hand, he was unsure of the significance of his work in game development, which involves a large number of people working together. At that time, I had a fateful encounter with Haruka Kanjiya, a girl who develops indie games, at a game event I attended! Indie game development is so much fun! ? Dedicated to his friends, he gets stuck in the swamp of game creation!
