Doesn’t make sense... – Underwater Survival Simulator Review

Ok so I am the only man alive because whatever happened. Now I’m at this little house box thingy about to go underwater. Oh I’m under water and suddenly I can breathe underwater. Ok that doesn’t make sense. Also please add sea creatures such as fishes, dolphins, sharks, etc. When your underwater for too long, your health goes down. Add ancient ruins please. Anything adventurous to explore.
