Muscle growth RPG is a text based adventure game that has a 'heavy' emphasis on muscle gain, growth, and a touch of transformation. You may get squeezed, made fun of your little size or being forced to help your roommate grow bigger. She will try to find whatever resources or supplements to make herself grow, with or without your help. She likes you as his roommate, but won't be too happy about you trying to stop her from becoming too big for anything to contain her.
