Learn how to cherish valuable resources.” — App Store Feature ///// Introduction ///// Desertopia is a relaxing and therapeutic idle simulator where you can spend just 5–10 minutes a day transforming a barren desert island into a vibrant, thriving habitat — all at your own pace. Your goal is to care for the island and help restore its wildlife. Occasionally, you’ll need to pick up floating trash to keep the environment clean. You’ll also make decisions about events triggered by human activity. Will you allow a tour group to visit the island? Should you build a resort? Every choice you make will directly influence how the island develops. ///// Features ///// ・Storybook-style art: Simply watching the animals roam the island can feel therapeutic on its own. ・100+ animals: Desertopia features over 100 unique creatures and 25+ terrain types. More than 15 legendary species may appear under special conditions — some only during festivals and holidays! ・Weather and water evaporation: Water evaporation is a unique gameplay mechanic. You’ll need to summon rain regularly to maintain livable conditions for your wildlife. If neglected, the island will gradually revert to a barren desert. ・Multi-layered music: Enjoy rich, evolving background music that shifts depending on the area and the animals inhabiting it. ・Events: Cruise ships bring visitors and special events to the island, each with both benefits and drawbacks. How your island evolves is entirely up to you. //////////////////// This game contains in-game offers to purchase digital goods or premium items with real-world currency (or with virtual coins and other in-game currencies purchasable using real-world money), where players do not know in advance which specific items they will receive (e.g., loot boxes, item packs, or mystery rewards).
