The writing of channel 34 is perfect for me. Maybe it's not perfect for visual novels in general, some of which have a more dense writing, but for a sex game like this one the unique tone of the game, the well dosed scenes, the evolving plot among others, gives the game an undeniable quality.
When you compare it with other games that are either too serious for what's going on, or too light for there to be a minimum of narrative coherence between the sex scenes, your game is way above the norm.
