Dreamweight is an 18+ feederism / weight gain / breast expansion simulation game. You play as a Nebutori, a yokai from Japanese folklore disguised as a human. You move to a new seaside city and grow stronger by making the women around you eat and gain weight. By day you work, cook, hang out and feed them. At night you slip into their dreams, where the real fantasies happen.

Three adult women (Linda, Melissa and Lisa), each with her own personality that changes as she grows. Features include a feeding minigame, cooking, a part-time job, photo studio, shopping, relationship progression, Nebutori powers, skills system, a phone with chats/photos/weigh-ins, and a Memories gallery.
