Use the left and right arrow keys (or A and D) to nudge your character horizontally as you fall. On mobile, tap the left or right side of the screen to move that direction. Avoid spikes, narrow walls, and obstacles.
Collect optional gems for score bonuses. The game ends when you hit a wall or hazard.
Stay Centered When Possible - The middle of the shaft has the most reaction time for either direction; only commit to a side when the layout forces it.
Don't Chase Every Gem - One missed gem costs much less than one wall hit; only grab gems on your existing path.
Learn the Hazard Speeds - Some obstacles cycle predictably; staying alive means matching your moves to their rhythm rather than reacting after they appear.
Short Inputs Beat Holding - Quick taps to nudge are more controlled than holding direction; the character drifts farther than you expect on long inputs.
Don't Fight Speed Increases - When the shaft speeds up, your inputs need to anticipate rather than react; tighten your reaction window mentally.
