Someone I know on CR who's very into Japanese detective fiction just finished the game. Their thoughts (no spoilers):
Overall impressions (in non-logical order):
- My clear time: precisely 18 hours (in one single session... Did put it on standby and all of course, but never shut the game down until now... =_=)
- Definitely a GK team game, with a bigger theme for the whole game
- And they have troubles structuring that theme / overall storyline in a streamlined way
- I did like how they tried to build on the problems raised in GS4
- Kokone is a Mary Sue, from beginning until the end
- The second and third case I liked the best personally
- Great music overall
- Animation was pretty much useless...
- Super easy
- 'Cameo's/recurring characters are handled badly (not as in personality, but as in tying them up to the plot)
- Odoroki/Apollo's role is awesome in this story. They should have done this to him in GS4
