567FLume

567FLume is a light observation puzzle game that challenges your visual perception in a unique way. Unlike traditional spot-the-difference games, TactLume presents a single geometric scene illuminated by consistent light sources, and your task is to identify the blocks whose lighting defies the established illumination model.

Each level displays a grid of luminous geometric blocks, all lit by one or more directional light sources. Most blocks follow the lighting rules perfectly, but one or more anomalies break the pattern. Your mission is to find these inconsistencies by carefully observing brightness gradients, shadow directions, and color temperatures.

Gameplay Mechanics:
- Examine the grid of illuminated blocks and identify those with incorrect lighting
- Tap the anomalous blocks to mark them as found
- You have three attempts per level; mistakes reveal the anomaly with visual feedback
- Clear all anomalies in a level to progress to the next challenge

Progressive Difficulty:
The game spans 100 meticulously designed levels across 10 chapters. Early levels use simple 3x3 grids with a single light source and obvious brightness differences, helping you build confidence. As you advance, the grids expand, light sources multiply, subtle color shifts emerge, and blocks evolve into more complex shapes with rounded surfaces and self-illuminating properties.

Daily Challenge:
A new puzzle is generated every day, offering fresh content for players who have completed the main campaign. Each daily challenge combines random elements from the game's lighting models to create a uniquely difficult puzzle.

Progress and Mastery:
- Track your completion across all 100 levels
- Compete against your own best times for each level
- Earn the Golden Badge by clearing every level without a single mistake
- Unlock chapters in the Light Encyclopedia to learn about each lighting model

Visual Design:
TactLume features a dark, focused interface with low-saturation luminous blocks against a deep background. The clean design eliminates distractions, allowing you to focus entirely on the subtle interplay of light and shadow.
