WASD to move, whole point is to reach 100.02 depth, and avoid the hazards that reside amongst you. There are 2 hazards to look out for. the easiest being the siphonophore, found at depths 30-50 and all you need to do is move out the way and wait till it passes. And the Bobbit Worm, at depths beyond 99. I'm not telling you how to avoid it. Nevermind I told you how to avoid it.
Play This Game If You Are Unemployed! Every now and then a sea creature will pop up, it's nothing, it's only meant to add life and make you not feel alone. I know 1 thing that will spawn in the deep will fool you.
