Blek

Blek is a puzzle game about connecting dots by drawing a doodle. Each of the 60 levels contains an area with a few coloured dots. To complete a level they need to be hit by a black line, drawn by the player as a free-form doodle of a limited length. When hit they disappear. When a doodle is finished it is launched in the directions drawn by the player and the pattern is repeated. It also takes into account the speed of drawing. When the doodle reaches the left or right side of the screen it bounces back, offering additional opportunities to hit all dots. When it reaches the top or bottom part of the screen it disappears.

Later levels introduce black dots that remove the doodle immediately. Some levels are filled with many black dots and the player needs to aim and draw strategically to avoid them. It is played in a minimalist environment inspired by the German Bauhaus design.
