The heroes of Squid 7 Challenge are lucky because they made it to the seventh round of challenges. The daredevils, among whom is your hero, managed to successfully cut a figurine out of Dalgon sugar candy, pull the rope over the abyss to their side, cross the glass-tile bridge at the risk of their lives and overcome other troubles. The seventh test is to test your natural instincts and responses. Watch the circular scale in the upper right corner. If it fills with red, stop the character immediately, otherwise they will be shot. The important thing is to just get to the red border and survive the Squid 7 Challenge.
