There are a lot of things in the original game that I don't agree with. There is also a lot of content that ends rather abruptly. I've tried to avoid changing very much in the original game aside from fixing bugs and removing failure paths that I don't agree with. I've also made numerous translation improvements in the original game.
The vast majority of my content is supplemental or complimentary to the existing story. I try not to interfere too much with the original game. I have added two new paths to the game - Foxy "nymphomanic" path and Tamara "Fuck Toy" path. The reason I try not to interfere too much with the original game content is because the author of the game is still adding content. I don't want to finish something he left undone only to have him finish it later on. I hope that makes sense.
I agree with you on most of your points. Thank you for your feedback and support!
