## What is Circuit Challenge?

CIRCUIT CHALLENGE is a tile-based puzzle game inspired by Chip's Challenge and classic puzzle games of the early '90s, reimagined for modern iOS.

You are a recovery bot sent to restore a corrupted system. Navigate 100 meticulously designed boards filled with hazards, enemies, and logic puzzles. Every level is a test of planning, reflexes, and problem-solving.

GAMEPLAY FEATURES

100 Boards across 56 difficulty tiers: from tutorials to near-impossible challenges
Strategic Hazards: Static zones, ice slides, fragile traces, conveyor belts, and minefield explosives
Enemy AI: Five unique enemies with distinct behaviors—wall-followers, bouncer patterns, and player chasers
Puzzle Mechanics: Magnetic codes unlock firewalls, hidden chips require block manipulation, toggle gates rewire your path
Accessibility: Progressive unlock system lets you tackle boards at your own pace
Level Codes: Resume from any completed board using unique 6-character passwords
HOW TO PLAY
Collect all chips to reach the exit before time runs out. Pick up colour codes to pass through matching firewalls. Avoid or shield yourself from enemies. Some challenges require multiple attempts to solve the puzzle.

17 LEVEL TYPES
Mazes, speed challenges, enemy encounters, block puzzles, teleporters, and more—each with distinct mechanics and colour-coded visual hints.

Built with SpriteKit • Supports iPhone & iPad

Recovery awaits. Are you ready?
