Acrophobia ball 2 is a 3-D arcade game where you have to dangle over an abyss and test your reaction. The goal is to collect all the crystals in each of the ten levels. But it is not as easy as it might seem at first glance as the levels are filled with dangerous traps and difficult obstacles. It will take you more than one attempt to clear each level for sure. It’s fun to play, especially since the passage of each level can be attempted an infinite number of times.
