A very lovely tale which wraps in mystery perfectly with the clue system. It doesn't struggle to place events in the right place, and the overall pacing and framework I think, was close to if not a total mastery of the Ren'Py engine.
The characters are memorable, and once you figure out their stories you get a better read on not only them, but the MC's attitude insofar how he works with/against them.
The music is well suited and fits perfectly with the clue system, albeit some noises and themes may be repetitive after a while.
The morality of the MC is very much one-track. It's a race against the stats, which allow you to do more sexual things with other characters. The fundamentals of the game surrender to this, so its not a problem, but understandably frustrating if you wanted to be more evil or more righteous as you progress through the game.
There are moments where you can really feel the MC's despair, and when his world does collapse around him, it still means a lot even if for all intents and purposes, he gets reincarnated until he chooses not to be when its all said and done.
