This ND game takes place in River Heights, Nancy's hometown. The setting seems pretty cool at first but gets repetitive traveling by car from location to location. The locations you do go to are fairly small with not a lot to do, most of the game is running between 3 different locations, retreiving one item, going back to the police station to drop off the item for Nancy, have Nancy analyze it, then trade off to another character... You are Nancy's errand boy in this game. The running back and forth (you use multiple characters outside the jail, and one can be more capable than another at certain tasks) makes the environment less immersive than past games. I prefer the more exotic locations, not boring suburbia.
While at first the ability to play multiple characters outside of Nancy (Ned, Bess, George) sounds new and different, I agree with a previous review that it gets very tedious very quickly. You have to go through Nancy everytime to make a switch, you can't switch freely between characters.
This game had less puzzles than previous games, and was furthered more by conversation/dialogue prompts. Add that into the fact that you have to leave each location, get in a car, watch the car travel to a new location, and then talk to the character at the location...it becomes boring.
Overall I'd say the plot and environment of this game is weaker than others. This is probably my least favorite ND game that I've played, and was shorter than some of the others.
$6.99 is not a terrible price for the game however, and if you're a fan of ND and want to try it out anyway, you should.
Lastly, the puzzle in Alexei's shop murdered my eyeballs. Thankfully after enough tries it just stops timing you. How you could possibly complete that by the top time I have no idea...
