Duo - Orb Mastery
DUO is an innovative dual-orb physics game that combines precise control with strategic positioning. You control a purple leader orb while a pink follower orb follows through realistic tether mechanics. The game features an overdrive system where fast movement generates explosive yellow power, unique crystal defense mechanics, and progressive difficulty scaling. Experience the perfect balance between precision control and explosive overdrive power as you master tether physics, build combos, and achieve streaks in this challenging arcade experience.
How to Play
Master the ultimate dual-orb physics challenge in DUO! Control a purple leader orb with your mouse/touch while a pink follower orb follows through realistic tether physics. Generate explosive yellow overdrive power when the follower orb moves fast enough (speed > 15). Only the overdrive orb can destroy falling crystals - miss one and it's game over! Master tether control by holding your input to shorten the connection (40-150px range) for strategic positioning. Face three crystal types: regular purple crystals (1 point), golden bonus crystals (5 points), and rainbow special crystals (10 points). Build combos, achieve streaks, and unlock achievements like 'Combo Master' and 'Streak Master' while surviving increasing difficulty with faster crystal spawns every 10 seconds!

Pro Tips
Master the tether mechanics - hold input to shorten tether for strategic positioning. Generate overdrive power by moving the follower orb fast enough (speed > 15). Only the yellow overdrive orb can destroy crystals. Build combos by destroying crystals consecutively. Use tether length strategically to position the overdrive orb for optimal crystal destruction.

Frequently Asked Questions
How do I generate overdrive power and what does it do?
Overdrive power is generated when the pink follower orb moves fast enough (speed > 15). The orb turns yellow and gains the ability to destroy crystals. Only the overdrive orb can destroy crystals - the regular pink orb cannot. Fast mouse/touch movement is key to maintaining overdrive power.
How does the tether system work and why is it important?
The tether connects the purple leader orb to the pink follower orb with realistic physics. Hold your input to shorten the tether (40-150px range) for strategic positioning. The tether stretches and creates tension, affecting the follower orb's movement. Use tether control to position the overdrive orb optimally for crystal destruction.
What are the different crystal types and their point values?
Regular purple crystals are worth 1 point, golden bonus crystals are worth 5 points, and rainbow special crystals are worth 10 points. Special crystals have pulsing rainbow effects and are rarer. Focus on bonus and special crystals for higher scores, but don't miss any regular crystals as they cause game over.
How does the combo and streak system work?
Build combos by destroying crystals consecutively. Streaks are created by destroying crystals within 1 second of each other, with bonuses up to 5x multiplier. The combo system rewards consistent crystal destruction, while streaks reward rapid successive hits. Both systems contribute to your final score.
What achievements can I unlock and how do I get them?
Combo Master: Achieve a 5-crystal combo, Streak Master: Achieve a 10-crystal streak, 1000 Points: Reach 1000 total points. Achievements appear on screen when unlocked and provide recognition for mastering different aspects of the game.
How does the difficulty progression work?
Difficulty increases every 10 seconds (600 game frames) with faster crystal spawn rates. The spawn timer decreases from 60 frames to a minimum of 30 frames, making crystals fall faster and more frequently. Special events spawn crystal clusters every 20 seconds for additional challenge.
What happens when I miss a crystal?
If any crystal reaches the bottom of the screen, the game ends immediately. This creates high-stakes gameplay where you must destroy every single crystal. The game over condition adds tension and requires consistent performance throughout the entire game.
How do I control the game effectively on mobile devices?
Mobile devices have optimized controls with larger orb sizes (18px leader, 22px follower) and adjusted tether lengths (130px max). Touch and drag to control the leader orb, hold your finger down to shorten the tether, and use fast movements to generate overdrive power. The game is fully optimized for touch interaction.
What's the best strategy for achieving high scores?
Master tether control to position the overdrive orb strategically. Build combos by destroying crystals consecutively and maintain streaks for multiplier bonuses. Focus on bonus (5pt) and special (10pt) crystals when possible. Use tether length to create optimal angles for crystal destruction. Practice fast movement to maintain overdrive power consistently.
How do the physics and collision mechanics work?
The game uses realistic physics with momentum, damping, and collision detection. The follower orb has velocity and acceleration, with damping applied to simulate realistic movement. Collision detection occurs when the overdrive orb touches crystals, triggering destruction effects, particle explosions, and screen shake for visual feedback.
