thank you for the advice
You use the arrows keys or WASD
For controlling the sub there is a steering wheel on the right side and you don't catch the fish just scan them
You just keep the fish on screen and then it will scan it after a bit and the name of the fish appears on the radar
Yeah sorry about the mouse thing it's just the way I made it was better for using "E" and also there isn't anything to do besides scan fish
