■ Game Features
〇 Strategic Battery Control
Slide and rotate the batteries falling from the top to position them perfectly. When the contact surfaces (positive and negative terminals) match in both type and color and three or more batteries connect, they instantly disappear in a gratifying chain reaction!

〇 Variety of Battery Types
Batteries of different sizes and shapes (like AA, AAA, etc.) appear. Assess their characteristics and stack them strategically to score high points!

〇 Stunning Effects & Increasing Difficulty
Enjoy dazzling effects and explosion animations when batteries clear, enhancing the thrill of chain reactions. As you reach certain scores, faster-falling obstacle batteries appear, demanding even sharper strategy and reflexes.

■ Game Overview
"Battery Stack - Electric Charge" is a puzzle action game where you control various sizes and shapes of batteries falling from the top of the screen. Each battery has randomly assigned "＋" and "−" terminals on its top and bottom, with the terminal positions changing based on the battery’s orientation. Use left/right movements, acceleration, and the central button to flip the battery’s orientation so that the contact surfaces align. When three or more batteries connect with matching colored and opposite terminals, they clear in a chain reaction, earning you points. Additionally, when you reach certain scores (starting at 200 points and every additional 200 points), faster-falling obstacle batteries drop; once fixed, they explode and trigger chain checks, acting as obstacles on the field.

〇 Difficulty Selection
• Choose your difficulty when starting the game:
- Super Easy… 2 terminal colors.
- Easy… 3 terminal colors.
- Hard… 4 terminal colors.

〇 Game Over Condition
If batteries stack up into the hidden area at the top of the field when fixed, the game is over.

〇 Controls
• Keyboard (supports hardware DPAD)
← / 4 / S: Move left, → / 6 / F: Move right, ↓ / 2 / C: Accelerate fall, Center key (DPAD Center) / Space / Enter / 5 / D / A: Flip orientation
• Touch Controls
Touch the left/right areas of the screen to move, the bottom third to accelerate the fall, and the center (or bottom button) to flip the battery’s orientation.

〇 Scoring and Speed
Clearing batteries earns points based on their type, and as your score increases, so does the falling speed, raising the difficulty. Furthermore, obstacle batteries are introduced at fixed score intervals, making chain formation even more challenging.

■ Who Should Play?
If you aim for high scores with swift decisions and precise touch controls,
if you’re excited by exhilarating chain reactions and visual effects,
or if you’re seeking a fresh gaming experience that fuses puzzle and action,
stack your batteries into the ultimate tower and unleash a chain reaction frenzy!
