A new version is live! The game is now more challenging, and new items have been added. Fly with a cute bird and help it stay light! Air Dieter is a simple and fun hyper-casual game where you eat food, lose weight, and try to reach the next stage. Easy Gameplay • Fly and lose weight: Keep flying to burn calories. • Eat smart: Junk food (pizza, burger, chicken box, donut) increases weight. Vegetables, Water and diet medicine help reduce weight. • Be careful: If the bird gains too much weight, the game ends. If the bird reaches 5kg, you clear the stage. Simple Rules, Big Changes • A heavier bird becomes bigger and slower. • A lighter bird flies faster and feels better. • Easy to learn, but you need balance and timing. Light Strategy • Diet medicine works fast but lowers Wing Muscle. • As stages increase, junk food appears more often, and healthy items appear less. • Make smart choices to keep your bird in good shape. Fun Leaderboards • Number of Birds (Stages Cleared) • Body Fat (%) • Wing Muscle (%) • Energy Level (Kcal) Try It Now! Simple, cute, and enjoyable for all ages. Fly, eat, and manage your bird's weight. How far can your bird go? ** If you experience sound issues during game play, please turn off the device’s mute switch. **
