If it is not possible to work in normal laboratories, scientists create them in their homes, setting aside a separate room for this. Doctor Ku, the hero of the game Doctor Ku The Cellar, has a laboratory in his basement. He had just begun to furnish it and was in the process of furnishing it. He moved some things, and then the door to the basement accidentally slammed shut and the doctor was trapped. There is no window in the basement and he cannot get out. You need to find a spare door key; it can be hidden in the basement among old things. Help the hero, no one knows that he is here and no one will come to the rescue except you in Doctor Ku The Cellar.
