Rainbow Ball - Power of Light

Rainbow Ball - Power of Light delivers a unique 3D ball-rolling experience designed by developer Sasaki Keisuke. The game combines simple one-finger touch controls with sophisticated physics simulation across 29 handcrafted stages divided into 6 thematic worlds.

The core gameplay revolves around precise ball manipulation using touch gestures. Players control six differently coloured balls including pastel pink, sky blue, saturated orange, grass green, lemon yellow, and pale purple lavender. Each ball features realistic gradient shading with highlights positioned at the top-left, creating authentic 3D depth perception against dark backgrounds.

World progression structure: The game begins with space-themed corridors featuring vertical dark grey stripes creating perspective depth. Players then advance to World 2 "Secret Garden" with dense green misty atmospheres and tropical plant silhouettes. Later worlds introduce night sky environments with bluish-tinted black backgrounds and Saturn-like planets with detailed ring systems.

The three-star collection mechanic adds replay value to each stage. Bright yellow 5-pointed stars with glowing halos are strategically placed in challenging positions requiring mastery of ball physics. Stars typically appear in formations like top-left, top-right, and bottom-left corners, demanding careful route planning.

User interface design: Two blue 40x40px squares anchor the top corners. The top-left displays a white snowflake freeze icon with the number 90, whilst the top-right houses an 8-toothed gear settings icon. The bottom control panel features five icons including circular arrow restart, two-bar pause, speaker sound control, and four-arrow fullscreen expansion.

The game includes character portrait system with circular frames in varying colours including pink, greenish, and brown borders. Each portrait displays character silhouettes with adjacent information symbols marked by the letter "i", suggesting collectible character progression elements.

Accessibility features: The skip function specifically addresses first-time action game players, allowing progression past difficult stages without frustration. This design choice makes the 154.6 MB download accessible to casual gamers whilst maintaining challenge for experienced players seeking 100% completion.

Technical specifications: Requires iOS 11.0 or later for iPhone and iPod touch. Mac compatibility demands macOS 11.0 with Apple M1 chip. Apple Vision support requires visionOS 1.0. The game maintains smooth performance across all supported devices with optimised ball rolling animations and physics calculations.

Visual atmosphere combines radial gradients creating lighter centres transitioning to darker edges on the primary dark purple backgrounds. This technique generates subtle centre glows that enhance the "Power of Light" theme referenced in the title. Green forest levels utilise limited visibility fog effects for mysterious exploration gameplay.

The level completion system displays clear feedback through light blue semi-transparent windows showing "World-Stage Clear" notifications. Celebratory stars surround completion messages, providing satisfying visual rewards for stage mastery. Version 1.0.4 includes bug fixes and performance improvements ensuring stable gameplay across all 29 stages.

Developed by Sasaki Keisuke, the game represents a portfolio of Japanese-developed mobile titles focusing on accessible mechanics with depth. The free-to-play model with no data collection ensures privacy-conscious players can enjoy the complete experience without concerns about personal information handling.
