Tips from The CD-i Collective.
Great work from Gir Draxa.
Avoid the ink blotches on your line:
You cut a line and the ink blotch is now hot on your tail?
Press buttons 1 & 2 in the same time (or button 3 from gamepad) to put the game in PAUSE.
The ink will start moving around the screen in a screensaver style pattern, wait a few seconds and return to the game.
Your line is gone but you are safe.
