This is our new franchise. It is a combination of a picture book and a game, featuring a warm and soothing mood and a rich story. A Long Time is a story about love and promises. To complete the story, you need to clear the obstacles to let the red line of memory flow through the pages by moving the blocks - which are actually fragments of emotions and flashbacks scattered over 60 years time of the protagonist's life. This is not only a game, but also an interactive picture book, which features unique artistic depiction, and a simple yet engaging way of interaction.
