BLUE REFLECTION Quartet centers on beautiful girl character growth and story exploration. Players need to spend time leveling up characters, gathering materials and unlocking side content, yet the game is only available on PC, making it difficult to continue your progress once you leave your desktop. OSLink solves this location limitation. As long as your PC stays powered on, you can remotely connect via your phone to enter the game and complete daily cultivation tasks. Detailed steps are provided below.

Step 1: Download OSLink and Pair Your Devices

PC Side

Visit the official OSLink website (https://www.oslink.io) to download and install the PC client, then log into your account. It is recommended to turn off automatic system sleep to avoid unexpected disconnections.

Mobile Side

Download the OSLink mobile app from the App Store or Google Play; installation packages are also available on the official website. Log in with the same account used on your PC, and your devices will automatically pair to establish a stable remote connection.

Step 2: Control Optimization Settings

1. Launch the Game

Start BLUE REFLECTION Quartet on your PC in advance. If the game is closed, tap the game shortcut inside the mobile OSLink interface to launch it remotely with one click.

2. Activate 60FPS PC Gaming Mode

Once your PC screen is streamed successfully, open the sidebar toolbar and turn on "60FPS PC Game Mode". You can either use virtual touch buttons or pair a Bluetooth gamepad for smoother controls.

3. Customize Cultivation-Oriented Key Layouts

Adjust the positions of confirm, back, page-turn and interaction buttons based on the game’s menu layout. You can freely resize buttons and tweak transparency. Combined with 3D camera controls, switching scenes and accessing cultivation panels become far more fluid.

4. Connect an External Gamepad

OSLink supports Bluetooth game controllers. Pairing a gamepad delivers nearly identical gameplay feel to playing directly on PC, perfect for long sessions of character management.

Step 3: Continue Character Progress Anytime

Once all settings are configured, your phone or tablet acts as a remote controller. Keep your PC powered on and connect through OSLink at any moment. Use fragmented free time to collect daily materials and level up characters; you can also organize cultivation resources during idle downtime.
