I cannot recommend Nonary Games.
There are a shitload of punctuation errors, the BEST plot twist is compromised due to being one screen, the dialogue is altered (vital to said plot twist), a few characters look derpy now, the music is altered, and now you're telling me there are no gruesome murder descriptions? Those were by far one of my favorite moments that set this apart from VLR.
This port is a [tornado fang]ing mess. The ending puzzle was crucial to the theme of the game, and they ruined that too.
The sudoku puzzle was a 9×9 grid.
Everyone who is a newcomer to Zero Escape, please stick with the original DS version of 999. And then get VLR on 3DS or Vita.
