In the vastness of space, Bobo—a wacky, red, and slightly naughty creature—has been left behind by his brothers. As the underdog of the "Reddish Land," he needs your help to navigate the cosmos and reunite with his family. Left Behind is a precision-based runner that tests your timing and patience. Travel across beautifully designed flat planets, each with its own gravity and atmosphere.
Ingenious Level Design: Tricky obstacles and varying planetary physics keep you on your toes.
5+ Beautiful Planets: Conquer Earth, the Moon, and beyond—each with unique visuals and BGM.
14 Collectible Characters: Unlock Bobo and his 13 brothers using stars earned during your runs.
Reflex Training: Sharpen your hand-eye coordination with swift, precision jumping.
Sharing Challenges: Compete with friends and share your high scores to see who is the ultimate space traveler.
How to Play: 1. Tap to Jump: Tap the screen to make Bobo jump over obstacles.
2. Swift Movement: Time your jumps to land safely on flat surfaces while moving between rotating or moving platforms.
3. Collect Stars: Pick up stars scattered across the planets to unlock new characters and worlds.
How to Win (Strategy):
Master the Arc: Learn the height of Bobo’s jump; some obstacles require early jumps, while others require waiting until the very last millisecond.
Focus on Rhythm: Every planet has a specific beat. Sync your movements with the BGM to find your "flow state."
Priority 1: Survival: While stars are tempting, surviving the level is the only way to unlock the next planet. Don't risk a run for a single star.
The 70/30 Rule: Data shows only 70% of players conquer Earth, and only 30% pass the Moon.
Unlock Characters Early: Some characters have slightly different visual cues that might make it easier for you to track movement against busy backgrounds.
Watch the Horizon: Look ahead of Bobo, not at him. Anticipating the next obstacle is the key to high scores.
Players Say: "Insanely addictive," "A little hard at the beginning but gets much smoother," "Great art style and music."
The Experience: Expect a mix of frustration and triumph. The game is designed to be challenging, rewarding players who can master the timing of each specific planet.
