[v1.3.0] Official Web Portal Renewal & Subpage Expansion

Update Applied: 2026-07-07

Portal Structure Revamp: We have significantly overhauled the main portal structure into a blog format to greatly enhance the provision of non-gameplay information. Users can now easily browse through vast and specialized in-game information.
Content Separation & Deepening: We have separated all content—including game lore, flight maneuver guides, aircraft specs and history encyclopedias, and in-depth FAQs—into dedicated pages. This dramatically increased text volume and maximized readability.
User Experience Improvement: To alleviate the inconvenience of frequent scrolling, we improved the UI by adding a Floating Navigation Bar that remains fixed at the top of the screen at all times.
Policy Compliance: Completely removed unnecessary pop-up ad logic that used to appear in-game. This prevents accidental touches (misclicks) in mobile environments and guarantees a clean play screen.

[v1.2.8] Performance Optimization & Rendering Engine Improvements

Update Applied: 2026-06-20

Graphics Engine Optimization: Resolved bottlenecks occurring in the rendering pipeline of the Three.js engine. By optimizing the Garbage Collection cycle during object creation, we significantly reduced frame stuttering during rapid weapon fire.
Texture Quality Adjustments: Added logic to dynamically adjust the texture resolution of background terrain so the game runs smoothly even on low-end devices.
Sponsorship Label Removal: Removed unnecessary text labels from in-game targets that were hindering game immersion, thereby creating a more realistic aerial combat atmosphere.

[v1.2.0] Mobile Virtual Controller & Payment Integration

Update Applied: 2026-05-15

Mobile Controls Introduced: We flawlessly integrated a touch interface where 'Virtual Joystick' panels automatically appear on the lower left and right of the screen when accessing via a smartphone or tablet. Now you can enjoy flying on mobile anytime, anywhere.
Payment System Integration: Integrated the official PayPal payment gateway API so global users can conveniently unlock aircraft and subscribe to the VIP pass.
Data Cloud Backup: Integrated Firebase Firestore cloud database so that gold acquired during play and purchase histories are not lost. Now, with just a Google account, you can recover your progress on any device.
