Don't Cross The Line

Don't Cross The Line is a puzzle game in which the player must connect lines to various boxes, from one identical box to another, without crossing the lines they draw in the process. There are roughly 50 stages in all. Depending on how quickly you complete each stage, you'll be awarded with a bronze, silver or gold award. To unlock additional stages, players must achieve a certain ranking in previous stages. Can you outwit the puzzles at hand and receive gold awards all around?
