aah, under the game in the description is says how to play the game and the goal. You are a diver trying to go back up to the surface! you only have your sonar to help you. so if you click (spacebar), it will illuminate the space for a little bit and trying to get back to the surface and avoid the sharks coming at you😊 and if SFX is too loud, press the escape key and go to settings to reduce the volume.
I hope you will enjoy the game!
