About this game

A Quiet Companion in a Moonlit Forest.

"Nighttime Tasmanian Devil" is a relaxing idle-raising game for adults where you leisurely raise a Tasmanian devil in a nighttime forest.

No complicated controls are required. All you need to do is "feed" and "watch over" it. Then, simply watch the devil relaxing in the moonlit eucalyptus forest, and it will grow bigger over time. It's perfect for taking a peek into the forest during work breaks or before bed.

■ Features of this Game
・Idle-raising Tasmanian devils living in a nighttime forest
・Simple care: just feed and watch over them
・Their appearance changes over time
・Quiet nighttime forest background music and moonlight
・Grows over time even when the app is closed
・Name them and make them your one-of-a-kind companion

■ Learn about wildlife conservation through raising your creature
The Tasmanian devil is the largest carnivorous marsupial still alive. This unique animal, found only on the island of Tasmania in Australia, raises its young in a pouch on its belly.

However, its numbers are declining due to the infectious disease "Devil's Facial Tumor Disease (DFTD)," and it is classified as "EN (Endangered)" on the IUCN Red List.

In this game, rather than presenting it as a scary story, you can gently connect with living creatures and their conservation by "caring for, learning about, and loving" the devil.

■ Points of Relaxation
- A round, plump body with a white band and round ears
- Completely Free (No In-App Purchases)
- Video ads may appear (they play occasionally between care sessions)
- No account registration or collection of personal information
- Offline compatible (no internet connection required)
- Relax your mind just by watching in the quiet night forest

■ Recommended for:
- Those who like Tasmanian devils, marsupials, and rare animals
- Those who want to relax with a relaxing, idle game
- Those who want to keep a pet but find caring for one difficult
- Those who want to learn about endangered species and the environment while playing

The devil will lose its energy if it runs out of food, so be sure to check on it once a day.
