How to play Harbor Hollow
This solo 2D game has three fixed maps with 16 geometric objects each. Start at radius 12. An object is absorbed only when it fits by size and lies fully inside your circle; absorbed area increases your radius. Clear all 16 within 45 seconds to finish a map. A shape enters the hollow only when it fits completely inside and your radius is at least 1.45 times its radius. Each collected shape grows the hollow by area: new radius = √(old radius² + 0.7 × shape radius²). Clear all 16 shapes in 45 seconds.
Controls
- Move with Arrow keys or W A S D, or move the pointer across the board; drag on touch. Space pauses or resumes (and starts when idle). R resets. Enter on Start begins.
Tips
- Absorb smaller objects first. Touching an edge is not enough; enclose the whole object.
