Underwater Ocean World — "Reef Rescue"
First-person underwater exploration. Clean 6 pieces of pollution from the coral reef. As trash is removed, coral sections "heal" — changing from gray to vibrant color. A friendly turtle NPC guides the player. Sunken treasure chest is a bonus find.
Design Intent
Serene activism. Slow movement (underwater feel), low gravity (0.1), muffled audio. The reward is visual transformation: gray dead coral blooming into color as pollution is removed. No timer, no enemies. The turtle is gentle encouragement.
