Touch Detective 2 1/2 review at 4 Color Rebellion.
"The original Touch Detective was a beautiful, though somewhat flawed, entry in the adventure genre. A year later, Atlus is back with the second entry in the series. We’ve seen several new adventure games on the DS; how does Touch Detective 2 ½ compare? Did SUCCESS manage to improve on the original game’s flaws?"
