- There are two different kinds of power-ups you can make use of in The Impossible Line - the miner's hat and the reveal. Generally speaking, you will get more use out of the miner's hat, as long as you take things very slowly and listen out for the proximity buzzer. Reveals should only be used in the most complex levels that are found towards the end of the game.
- There may not be a time limit in The Impossible Line, but we had much more success by moving the chalk in one continuous line, while the memory of the layout was fresh. If you stop, you increase the chances that you'll forget how the maze is laid out, and you'll more often than not have to pay for a reveal to get going again.
- Listen out for the proximity beeper at all times. This noise indicates that you are getting too close to a wall for comfort, and the more rapid the beeping noise becomes, the closer you're getting to failing the level! You can also use this circular meter as a visual aide. As the circle gets smaller, you're getting closer to a wall. By carefully steering around the screen, you can solve some complex levels with ease.
- Keep an eye out for any parallel lines at play in the map you're working on. If you know that there are parallel lines right next to each other, then you can use your existing chalk line as a guide for the next line you have to draw. Just make sure the lengths and widths of the obstacles are the same, and keep listening out for that proximity beeper.
