From the Game Manual:
Med Systems Software is proud to present THE INSTITUTE, a rousing adventure game by Jyym Pearson. You begin in an institution populated by a dwarf, counselor, guards, and other inmates. You can enter whole sentences as well as one and two word commands, as you strike to retain your sanity. You must escape, but the key to escape is not the building itself. Your dreams, brought on by a mysterious powder, hold the key to escape, as well as four whole worlds of bizarre characters and locations. It's like playing five adventures in one!
