Today (August 1 1), the strategic simulation game "Rena's Library" produced and distributed by ProjectMoon, a developer of Brain Leaf Company, was put on the Steam platform. The game was first launched on PC on May 15, 2020. In the game, the player will play the role of librarian to welcome the guests who come here. In the war of the library, the librarian will fight with the guests, and the defeated guests on the battlefield will become books to expand the library's inventory. In addition, after the book was put on the shelves, a limited-time promotion was launched at the price of 139 yuan, which supports simplified Chinese.
