The Vortex point games are generally the best of Carmel (Deathtiger) games, but this one was slightly worse then others because the plot made no sense.
There is nothing evil about using a statue to become 30 years younger and even stealing it from a person who is not using it. The thief was wise to steal it from fools who would lock it away. This statue could make a large part of humanity immortal. Granted this would cause some interesting social consequences and maybe the world is not ready for that. But still - locking it up and not keeping it for using was dumb from Kevin.
Anyway, the major plot hole is the circus director sitting in the Ferris wheel when he is not ready for age changing. Could have ambushed Kevin elsewhere.
