🌀 Gravity Ball

How to play

A purple ball sits in the bottom-left corner and a gold star in the top-right. You never touch the ball directly: holding the button pulls it toward your pointer, so steering means placing the pull ahead of where you want it to go. Red circles are hazards. Reach the star and the level goes up with a denser layout.

• Hold the mouse button on the canvas — applies a pull of 0.4 per frame toward the cursor. Faint rings show the field. Release and the ball coasts.
• Move the mouse — relocates the attraction point, which you can drag around with the button still held.
• Touch and drag — the same thing on a touch screen.
• Start button — begins a run and resets score, level and lives.

Scoring

Reaching the star scores 10 points times the current level, so the first star pays 10, the second 20 and the third 30. Each new level adds a hazard — the count is 2 plus the level number, placed at random. You have 3 lives and lose one whenever the ball touches a red circle, which also resets it to the corner with no speed. At zero lives the run ends.

Tips

• Pull in short bursts. Velocity accumulates and decays by only one per cent a frame, so a long hold sends the ball past the star into a hazard.
• Put the pointer beyond the star, then release early and let the ball drift the last stretch.
• Walls bounce at seventy per cent, so bumping an edge is survivable and is often the cheapest way to kill speed.
• Points scale with level, so protecting lives matters more than rushing the first few stars.
