• Clear: tap/click any object to remove it.
• Unbreakable (lock): new drawn objects become non-breakable.
• Color picker: sets color for new shapes.
• Pause/Resume: pauses or resumes physics simulation.
• ? Help (?): opens this help window.

Sliders

• Speed: controls physics simulation speed.
• Strength: sets break resistance for newly created shapes.
• Bomb: controls explosion power (radius/force/effects).

Tips

• On mobile, drag with one finger on canvas to draw shapes.
• Strength and Unbreakable apply only to objects drawn after changing them.
• Bomb and Clear are tool modes and are mutually exclusive with drawing mode.
