Very strong sequel that builds on the first one's narrative well, the loop of visual novel - investigation - trial just works and there's a variety to its mechanics.

It wants to be Raymond Chandler when it's actually John Woo.

Think I slightly prefer the Zero Escape series but this one still has a good premise, the calendar structure helps the excesses of the teenage dialogue go down and I enjoyed the investigation and trials. Hifumi deserves his own spin-off.
