Controls: Click / touch and drag on the canvas to draw ink lines. They become solid surfaces. Guide the ball to the green goal. Ink is limited per level.
Ink Roll is built around a mechanic I designed specifically for this site: your drawings are physics. Every line you sketch with the mouse or your finger becomes a real, solid collider in the world the instant you draw it. A ball drops under gravity, and your ink is the only tool you have to catch it, deflect it, and roll it into the goal. The catch is that ink is a limited resource per level, so you can't just flood the screen — you have to draw the right ramps and bowls with the ink you've got.
Press and drag anywhere on the canvas to lay down ink; release to stop. The ball is always live and reacts to your lines in real time, so you can draw mid-fall to save it. Reach the green goal circle to clear the level. Use "Reset Ball" to drop the ball again from the start (your ink stays), or "Clear Ink" to wipe your drawing and refund the ink budget.
Gentle slopes roll the ball; steep slopes stop it. If the ball keeps bouncing off a line instead of rolling along it, redraw that line at a shallower angle. Build a funnel above the goal rather than trying to land the ball precisely. Because ink is scarce, one long well-placed ramp beats several short scribbles. Watch where the ball naturally falls first, then spend ink only where it's needed.
