I would like to apologize to those who could not complete the game due to, for some reason, poor generation of closed doors and keys. With this update, in theory, now 100% can go to the end. Please test new algorithms and try to complete the game now. You can write about all the shortcomings in the discussions.
Also:

• The volume of the sounds of the doors of a large cabinet is increased
• Added sounds for rack doors
• The volume of the sound of the sliding shelves is increased
• Removed duplicate doors that appeared stuck and prevent the game from passing
• The number of useless keys on each floor is reduced from 3 to 1
• The spawn of bags is shifted one floor higher, now they can be found starting from the 7th floor
• Added additional light for bags and keys so that they can be better seen if they are generated under the trash
• The number of closed doors is slightly reduced.
• Improved chain of sequences of closed doors
• Now the chain of closed doors does not go further than 2 floors
• Slightly changed the position of furniture in the kitchen so that the stove does not interfere with the doors of the cabinets
