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).

Our 299RC, which studies cats, was researching fish with high nutritional value for cats. Our research revealed that ancient fish have abundant nutritional reserves that do not exist in modern fish. However, no one has ever raised a fish, much less a fish with a nihilistic face that has no idea what it is thinking... The researchers are a group of cat experts. No one knows how to raise a fish... The institute has decided that it is impossible to raise this nihilistic fish as it is! So, we need your help. We need your help in researching this nihilistic fish "BasPi". Right now, we can only provide a simple tank, common fish food, and an environment like that... As our research progresses, we will be able to add more equipment. Until then, please keep this "BasPi" alive and pass it on from generation to generation. In this tank, there are sometimes mysterious creatures that are after the "BasPi". Normally, this type of fish should be armored, but this "BasPi" is fluffy and unreliable. I have prepared some equipment for just in case. You will not be able to use them until you become an adult, but I hope that somehow you will survive the crisis with this equipment. Thank you very much. *This story is a work of fiction.
