I don't know whether this is how the game is supposed to work but I can only move forward, backward, up and down. I am unable to reach the location to get the black boxes but just based off what I have seen and what the game is about, it seems to have a good game mechanic of taking care of yourself and your friend, watching out for fish monsters through the radar and turning on and off the lights like FNAF and moving around to find black boxes. It would be cooler if the fish had a more horrifying look and some of the details in the game could have been made to look more aesthetically pleasing.
Thank you for reading my comment and I wish you good luck in your future endeavours.
