Ball – Fast‑Paced Arcade Action

Overview

Ball is a minimalist HTML5 arcade game where you control a red sphere navigating a bounded arena. Your mission is simple: chase the glowing green food, collect it, and avoid the ever‑growing swarm of hostile red enemies. Each bite of food spawns a new enemy, increasing the challenge while the game runs endlessly. Every six points a purple power‑up appears, granting either a temporary shield or a slowdown of enemies, adding a strategic layer to the frantic gameplay.

Key Features

• Intuitive Controls – Arrow keys or WASD on desktop; touch‑drag on mobile devices.
• Endless Scoring – The score rises with each food collected; a persistent high‑score tracks your best performance.
• Dynamic Enemy Behavior – Enemies move strictly horizontally or vertically, bouncing off arena walls. Their number grows with every food you eat, creating increasingly tight corridors.
• Power‑Ups Every 6 Points
  • Shield: Grants a 5‑second invincibility, visualized by a faint white glow around the player.
  • Slow: Reduces enemy speed by 50 % for 5 seconds, making navigation easier.
• Responsive Design – Optimized for both desktop browsers and mobile devices, with high‑DPI scaling for crisp graphics.
• Simple Yet Engaging Visuals – Gradient‑filled circles provide a clean, modern look without heavy assets.
• Automatic Restart – After a game‑over, the round restarts automatically, encouraging quick retry attempts.

Gameplay Mechanics

1. Movement: The player’s red ball moves at a base speed of 5 px per frame, multiplied by a speedMultiplier that increases slightly after each food.
2. Food Collection: When the distance between the player and the green food is less than the sum of their radii, the food is “eaten,” the score increments, a new food spawns, and a new enemy appears.
3. Enemy Interaction: Enemies bounce off the arena edges. If the player touches an enemy while the shield is inactive, the game ends.
4. Power‑Up Interaction: Colliding with a purple power‑up triggers its effect and removes the power‑up from the field.
5. Screen Wrapping: The player can travel off one edge and appear on the opposite side, adding a tactical escape route.

FAQ

Q: Can I play Ball on a smartphone?

A: Yes. The game supports touch input; drag your finger on the screen to move the red ball.

Q: How does the shield work?

A: When you collect a shield power‑up, a faint white aura appears around the player for 5 seconds. During this time, collisions with enemies are ignored.

Q: What happens when the “slow” power‑up is activated?

A: All enemies have their movement speed reduced by 50 % for 5 seconds. After the duration, speed returns to normal.

Q: Does the game keep my high score?
