Finger Twister
Finger Twister is a flash screamer. It asks you to place a left finger on the blue "L" circle and a right finger on the red "R" circle and to hold for more than 30 seconds without lifting them. After "BEGIN" is clicked, the circles move around but after 8 seconds elapses on Level 1, a picture of a Great White Shark with its mouth open appears on the background accompanied with a sudden whooshing sound.
