I will take your comments in good faith, I think the type of game you are looking for in terms of game design, slower corruption with more scenes building towards it with choices that allow you to control the degree of corruption is not present for this game. That does not necessarily make this a bad game, it just is different from what you wanted which is okay. Not everyone will enjoy the design choices made in the game. In this game, some routes are longer than others and you can see corruption take place at what I think a pretty decent pace (not slow or fast).The routes structure in this game I believe are not right and you are constantly locked from other events if you made the "wrong" choice, other stuff can easily happen in the same time but seem here are being treated only as show off and you are forced to make a choice (what is stopping the kid to do some stuff it does in a specific route, or what happen to other characters that are being introduced but never developed if not in their specific routes? They simply cease to exist).
This, plus many other things are not making the game more attractive to whoever is not at their first playthrough in h games...
As I said I will still play the game but feel really weird to play a full game in fractions where each route is not even that long.
What this game does instead is allows you to choose the different paths in which she can be corrupted, hence it locks you in once you have made certain choices. But the advantage of this design is that you get to see her in different contexts, corrupted in different ways by different circumstances, which some people very much enjoy. There will never be a perfect game, but hopefully you managed to still enjoy it at the end of the day.
