A 25-year-old man was taken to hospital with burns following the fire which broke out around 5pm local time.
Police and fire officials said they did not yet know what started the blaze in the escape room, which was reported in the early evening.
Mr Brudzinski ordered fire safety checks to be held at all "Escape Room" locations in Poland.
There are around 150 Escape rooms across the United Kingdom with more than 50 in London alone and the craze for escape room adventures has increased year on year since 2013.
He also said that the bodies of the youngster were found in a room near the fire.
He said firefighters who put out the blaze and other witnesses were being questioned.
Escape rooms have recently surged in popularity in Poland and across Europe and the world. What caused the fire has not been determined. Asphyxiation is the probable cause of the deaths. Local residents placed flowers and lights in front of the location, a two-storey house with a huge "Escape Room" sign in front. The five joyful girls entering the life have been torn out of life.
The deaths have prompted an outpouring of grief in Poland, with Prime Minister Mateusz Morawiecki issuing condolences to the victims' relatives and a day of mourning announced in the city of Koszalin.
