Key Features
- Physics-based defense: Your sketches gain mass instantly. If you draw a thin bridge, it will snap under the weight of a heavy boulder.
- 3D depth perception: Objects fall in a 3D space. You have to account for the perspective shift or you will miss the protection zone.
- Cute character panic: The tiny guys react to the danger. Watching them scramble makes it much worse when you fail to save them.
- Brain-burning geometry: You are limited to one single stroke. Every corner you draw counts against your survival odds.
How to Play
OneLine: Mastering the draw
Use your mouse or finger to sketch a line that acts as a physical barrier. Once you lift your hand, the ink hardens into a 3D structure. How to play OneLine involves predicting where the debris falls. You need to angle your shapes so rocks bounce off rather than crushing your fragile guys.
Why OneLine controls matter
OneLine controls are simple, but the timing is brutal. If you draw your line too far from the character, the physics might glitch and let a bomb slip through the gap. A common mistake is drawing too many lines at once, which makes the game freak out and drop your frames.
Surviving later OneLine levels
The difficulty spikes once the rain starts coming from multiple angles. You have to draw fast and thick to stop the pressure. Don't get cocky after clearing ten stages, because the final levels turn into a chaotic mess that makes you regret your earlier, sloppy drawings.
