Honestly, I love the Vortex Point series, and was really disappointed to find that it didn't work at all... That is, until the fourth or fifth time I checked after a number of weeks, it miraculously worked.
It was great, just like all the others.
Finished in 28:22. A great length of time for something like this.
The last half a star is for making me wait.
Remember, always drink your holy water and make sure it works. :?)
