## What is Afterimage Memory?

Afterimage Memory is a simple brain-training game that challenges you to memorize numbers for a moment, then find the one that changed.

Look at the numbers on the screen, remember their positions, and tap the number that is different from your memory. The rules are easy to understand, but each stage asks for sharper memory, wider visual attention, and faster reactions.

Stage Mode lets you progress through 15 stages with increasing difficulty. As you clear stages, the number of items and grid density increase, creating a steady memory challenge.

Score Challenge is built for high-score runs. Keep your streak alive, build combos, and aim for a new personal best. Game Center rankings, score sharing, and satisfying effects make it easy to return for daily brain training.

Main features:

- Tutorial stage explaining controls, score, difficulty, and time limit
- 15-stage Stage Mode with progressive difficulty
- Score Challenge for high-score runs
- Combo display, best-score effects, and high-score celebration
- Haptic feedback for correct and wrong answers
- Sound and vibration settings
- Game Center leaderboard support
- Share your results

Afterimage Memory is designed for quick sessions, spare moments, and daily memory training.
