So hey if you're a Phoenix Wright fan (or possibly even Hotel Dusk fan), then you'll probably like this game.
Your character is a ghost who manipulates stuff, so you end up trying to manipulate and build these Rube Goldberg-esque contraptions to try and achieve certain goals. It's very puzzle-orientated, but most of it is trial and error. Timing is also important too. It's not very hard, but it's satisfying to solve because everything connects together and it's just Ahhhh so that's how it works!
The reason I said you'd like it if you like Phoenix Wright is that the dialogue and the story is kinda similar. Wacky Japanese characters, murder mysteries to resolve etc. The story is pretty good, the dialogue is fantastic (though perhaps not quite at the PW level).
Oh and the animation is fantastic. Honestly some of the best graphics I've seen on the DS. It's so smooth and beautiful.
So try it out! You can try a
demo here.
