This game has very high highs, and very low lows. The story expands upon what 999 built upon, and uses the timeline mechanic to its fullest here, the problem is the story will just go off the deep end far too many times, and slow moments are not fun. There are plenty of cool revelations, but certain routes are super similar, and you'll see the exact same things with small alterations. Some plot twists are just straight up bad, and have several reasons for why they could not work.

The puzzles are really fun, the characters are great (mostly), and is a nice successor to 999, but at times, the story doesn't know when to quit.
