## What is Tippy Brim?

Brimful — A one-tap physics game that puts the science of surface tension at your fingertips.

HOW TO PLAY
1. Pick one of three liquids in Practice mode, or take on a hidden liquid in Challenge mode
2. Hold the faucet to fill the glass to the rim
3. The faucet swaps for a dropper once the cup is full
4. Tap to release single drops and grow the iridescent dome
5. Hit "I'M DONE!" to lock in your score — spill, and the score resets to zero

TWO MODES
■ Practice — three liquids to master
• Alcohol: weaker surface tension, smaller dome, fast-settling ripples. Beginner-friendly
• Water: balanced standard
• Syrup: stronger surface tension, taller dome, long-lasting ripples. Advanced

■ Challenge — 7 mystery liquids + random cup size
• Viscosity, oscillation, and dome height change every round — drawn from 7 hidden variants
• Cup size also rolls between XS / S / M / L / XL
• Anti-repeat ensures no two consecutive rounds share the same liquid or cup size
• Scoring is fair across configurations: bulge² × time multiplier × tap bonus

THRILL
• Past 70% bulge, random air currents start rocking the surface
• Idle long enough and the cup may spill on its own
• In the dropper phase, score decays 3% per second after a 3 s grace
• Faster taps boost the tap-bonus multiplier (×0.7 to ×1.30)
• Challenge scores above 2000 are masked as "????" — you only see the truth when you cash in

VISUAL
• Iridescent soap-bubble dome that catches pink, lavender, and peach light
• Warm cream paper aesthetic with a glassy cup centerpiece
• Custom physics engine renders the faucet, dropper, and droplets in real time
• Meniscus clings to the rim, oscillates, and breaks with believable detail

DESIGN
• Tap and long-press only — no shaking, no tilting
• Fully offline. No network access, no ads, no in-app purchases
• Bilingual JP/EN with preference persisted across launches

Thank you for playing Tippy Brim!

This update improves clarity and stability:

• Added an on-screen hint for the dropper phase so the tap control is always visible.
• Streamlined the Challenge HUD by removing a counter that did not affect your score.
• Reworded and reorganized the result screen for clarity.
• Added practice-mode scoring to the how-to guide.
• Improved the legibility of small text.
• Fixed a rare case where the screen could stop responding right after a round ended.
• Fixed score decay continuing while the app was in the background.

We hope you enjoy the update.

### 1.0.2 — 2026-06-14

• Improved the Challenge-mode score display 
　— watch your score climb during play, while the final figure stays hidden until you cash in.
