Wow. I am absolutely blown back by this game. This could very well be the best NTR game I have ever seen. You, good Hangover Cat, really are a master of your craft.
This game has all the core aspects done almost perfectly. The story is great and hits like a truck. The art is beautiful, the multiple styles actually working pretty damn well. H-scenes are given enough attention and effort they deserve, making them much more dynamic thanks to movement and sound, so much better then a still picture with a few variations. Perhaps the greatest and best done part is the mystery. NTR is a very story tied thing, and mystery, unseen things and revelations are such valuable components. The first POV play of Sam is exceptionally good already on its own, that's how good writing and execution are.
While Drew being the main culprit is somewhat guessable since there are hints and only two suspects (one of which is a clear red herring), I still feel the mystery works so damn well. I feel like there would be great potential for a similar scenario, but that would have maybe 3 suspects, which would make the mystery harder to guess and very interesting.
Keep this up, Hangover Cat, you clearly understand what you are doing so keep true to your own vision. I am sure your next project is going to be great, never mind the ones in the distant future.
