CandyPotion

CandyPotion is an offline iPhone color-ratio puzzle game set in a candy potion shop. Each level gives you a named order, a Target color swatch, and
a Current potion color that changes as you add Red Syrup, Green Mint, and Blue Dust.

Tap ingredient buttons to build the right RGB mix, use Clear when the cauldron needs a reset, then tap Verify to compare your potion against the
customer order. Early levels teach simple red, green, and blue recipes such as Berry Glow, Mint Spark, and Sky Sugar. Later orders combine larger
ratios, tighter color judgment, and the same 60-second limit.

Features:
- Potion shop brewing board with Target and Current color swatches
- Red Syrup, Green Mint, and Blue Dust ingredient buttons
- Central cauldron preview that updates as the mix changes
- Verify button that checks the RGB ratio against the customer order
- Clear button for restarting the current brew without leaving the level
- 50 local levels with locked progression through Level Select
- 60-second order timer with success and failure result overlays
- Local progress and Settings saved on device with NSUserDefaults
- Fully offline play with no login, ads, analytics, tracking, or in-app purchases

CandyPotion is built for short iPhone puzzle sessions where every order asks you to read the target color, tune the ingredient ratio, and bottle
the right potion before time runs out.
