## What is Nanda Sense?

A high-speed reaction game where shapes flash from top to bottom - your job is to identify what just fell. Fall time from 0.35 to 1.5 seconds, 3 to 6 multiple-choice options. Color is misleading: identify by shape alone.

[Fully Offline, Zero Data Collection, Zero Ads]
Everything runs on-device. No network traffic, no data collection, no advertising, no third-party SDKs. The app works without an internet connection - safe to hand to kids without worry.

[The Signature Feature: Your Own Drops]
Crop any photo from your iPhone album into a personal falling shape. Pets, favorite characters, logos, household objects - anything can become a drop. Up to 10 photos can be stored, each toggleable between Color and Mono silhouette. Mono drops fall as a tinted shape just like the built-in 13 shapes, removing color and texture cues to sharply raise the difficulty.

[13 Built-in Shapes]
Circle, triangle, square, diamond, star, pentagon, cross, hexagon, octagon, heart, ring, semicircle, crescent. Each spawns with a random rotation and one of three colors - but color is never a clue.

[4 Difficulty Levels]
- Easy: 1.50s / 3 choices (intro)
- Normal: 0.80s / 3 choices
- Hard: 0.35s / 5 choices
- Custom: 0.15-2.00s fall time + 3-6 choices, fully adjustable

[Session-Based Play]
Set 1-10 rounds per session. The summary screen shows your correct count and accuracy. A 100% run triggers a "Perfect!" celebration. The last three sessions are saved as history.

[Polish]
- 120Hz ProMotion-ready for the smoothest fall rendering
- Two visual themes: Cyber (neon, dark) and Soft (pastel, cream)
- Portrait + Landscape (landscape shortens the fall path - harder)
- Bilingual How-To-Play guide with JP/EN toggle

For anyone who wants to sharpen reflexes, kill a few minutes with a quick game, or build a personal reaction game from their own iPhone album.

Requires iOS 16+. Works without an internet connection.
