Some of the most Uchikoshi-ass Uchikoshi here. The kind of game where you just want to keep notes the whole way through to keep track of your theories and waht you've figured out.

Compared to AI, the characterization feels a bit weak. Maybe it's the escape game format that means that no one has a chance to really develop as a character outside the core events. The actual mystery plotting is satisfyingly tight though.

I can't even imagine playing this on any platform that's not a DS. The end game twist depends on it.
