Gravity Well
Flip gravity up or down to slip through a scrolling cave. Hug the gaps and never touch the rock!
How to play
- Press FLIP, the Space key, or tap the cave to reverse gravity.
- Your craft accelerates in whichever direction gravity currently points.
- Thread through the moving cave gap without touching the purple rock.
- The cave narrows and scrolls faster the longer you survive.
- Distance becomes your score; your best run is saved.
Press FLIP, Space, or tap the cave to invert gravity. Your craft falls toward whichever direction gravity points — flip at the right moment to slip through the narrowing cave.
How it works
Gravity Well is a gravity-flip cave runner. Your craft moves forward through a scrolling cave, and you flip the direction of gravity -- up or down -- with a single tap or click. When gravity points down the craft sinks; when flipped, it rises toward the ceiling. The cave walls undulate and narrow, requiring carefully timed flips to thread the gaps.
Momentum carries the craft briefly in the old direction after a flip, so you must anticipate a flip slightly early. The challenge increases as cave sections narrow and require multiple rapid flips in close succession.
Gravity Well rewards players who find the rhythm of flipping in sync with the cave's shape rather than reacting late to each upcoming obstacle.
Worked example
Surviving the first cave narrowing
- Begin the run and use the first open section to get a feel for how quickly the craft responds to flips.
- As the cave roof lowers, flip gravity down so the craft follows the lower wall's curve.
- When the floor rises, flip gravity up to lift the craft away from collision.
- Time each flip about half a second before the cave actually forces the new position.
- Stay near the vertical center of available space after each flip.
Passage through the first narrowing without a wall collision.
Common mistakes to avoid
- Flipping gravity too late, after the craft has already moved into dangerous territory.
- Over-flipping in open sections, which wastes time near the ceiling or floor and leaves no room to dodge the next wall.
- Treating each section independently instead of reading the coming cave shape two or three screen-widths ahead.
Key terms
- Gravity flip
- The core mechanic: reversing the direction gravity pulls the craft, causing it to move toward the opposite wall.
- Momentum
- The tendency of the craft to continue in its current vertical direction briefly after a gravity flip is triggered.
- Cave narrowing
- A section where ceiling and floor converge, leaving a smaller gap the craft must pass through.
Frequently asked questions
- How does the gravity flip work?
- Each press reverses gravity, pulling your craft up instead of down (or vice versa). Time your flips to stay centered in the cave.
- Why does it get harder?
- The cave gap narrows and the scroll speed rises as you progress.
