Author's Note
Hello everyone, I'm HAIM. This game is once again my own, encompassing the art, music, script, and programming. With the goal of ensuring that people around the world can enjoy this game regardless of language barriers, I deliberately challenged myself to create a text-free game, relying solely on visuals to help players understand the story and levels. This proved difficult, and it prolonged the development cycle. During this time, I also came up with more ideas, ultimately creating three endings (good, normal, and bad), giving the story greater depth.
