Greetings @FaxLab3D !
Operation Codename: Hong Kong Obscure looks really interesting!
When I first watched your video, I was amazed with the trippy lighting and the ghosted images. I wondered about the premise of the game and its general objectives, so I ventured over to your Steam page and discovered that some information has been redacted by a protective agency! 
I rather enjoyed reading the game info!
I’m assuming the point of the operation is to track your own path, explore freely, and then draw your own conclusions. Each person’s experience will be uniquely different from another’s. Is there any in-game incentive for the player to communicate their personal experiences?
What are the challenges you faced with achieving the 40fps standard that you were looking for? Are there any suggestive “guides” that will assist the player in uncovering which objects are interactive?
