⭐ Update v1.3


This update focuses entirely on improving user experience, device compatibility, and giving players full control over how the game appears on their screens.

Every phone has a different aspect ratio, different safe areas, and different gesture bars — so this update introduces a proper calibration workflow and a redesigned settings menu.


🎯 Screen Calibration System

A brand-new Screen Calibration mode has been added, allowing every player to manually adjust how the game fits their device.


Players can now:

- Adjust the playable area so nothing gets cut off on devices with curved edges or gesture bars

- Scale the screen up or down using intuitive on-screen arrows

- See real-time boundaries (“dead-zone outlines”) to make sure the entire game is visible

- Save their calibration so it loads automatically every time


This ensures perfect visuals on every display — widescreen, tall screens, hole-punch cutouts, tablets, anything.


⚙️ Simplified & Powerful Settings Menu

The Settings screen has been redesigned to be clean and beginner-friendly, while still offering advanced control.


🖼️ Graphics Quality

Players can choose between four levels:

Low – for older or low-end devices

Medium – balanced performance

High – enhanced visuals

Best – maximum quality (recommended for flagship devices)


The game instantly adapts to the chosen setting without needing a restart.


📐 Letterbox Options

Some players prefer a classic look with black bars, while others want the screen filled.


Now they can choose:

Black Bars (Letterbox ON) – preserves the original game aspect

Game Background Fill (Letterbox OFF) – uses in-game background to fill empty space

(perfect for fullscreen immersion)


🖥️ Fullscreen Stretch Mode

A new toggle allows the game to:

Keep the original aspect ratio (Default)


Stretch to full screen

– fills the entire display, matching the phone’s aspect ratio

– perfect for players who want a borderless, immersive experience


This mode is optional, since some players prefer accurate proportions while others don’t mind stretching if it removes black bars.


Summary

This update adds:

✔ Full screen calibration system

✔ Device-independent layout scaling

✔ New graphics presets

✔ Letterbox toggle

✔ Fullscreen stretch mode

✔ Cleaner, simpler settings UI


The goal: let every player tune the experience exactly how they want, regardless of device type.
