Visual novel game where the central concept is "Groundhog Day + the board game Werewolf." Has some insanely good writing in the trial sections and the character writing is stellar. Without spoiling anything, the only thing that might put some people off is the true ending. I personally thought it was good (not excellent, but overall made sense in context), but others may be put off by the themes, or the reliance on an odd plot device.

If you like stuff like Danganronpa or the Zero Escape trilogy you'll probably enjoy this as it is a similar ratio of absurd to insanely good writing. Just be aware this is a visual novel to the core (0 gameplay beyond the odd dialogue choice, all reading).

EDIT: The music in hindsight is a real show-stealer as it goes a long way to setting the mood. The trial theme as well as the hanging theme are both songs that will stick in my head for a bit.
