I doubt anyone meant to pick a fight. This is one of if not the biggest and most "historical" threads/games on this forum at this point, and it means surprisingly much to a large amount of people, me included. Seeing the game revitalized and having something to look forward to after so many years brings out excitement and passion in people. People reacting to what you're showing off is simply the result of said excitement. FrozenWolf and Raper Beast have been my favorites in this game since forever, and I'm sure it's the same for a lot of others as well, so of course people will be passionate about them. I joined this forum originally for specifically Fairy Fighting, and that's almost eight years ago now, so of course I'll react and want to be involved when you start talking about my favorite enemies in my favorite hentai game of all time!
But again, you do you. I'm excited for it regardless, even if I do find the removal of both dog/wolf like enemies to be a bummer. No matter what you do and we'll be excited for it, but you can't expect everyone to be 100% happy with every choice you make (or this game would've been dead in the water forever ago). The original will still be there regardless, and if you actually manage to finish this project of yours (you deserve all the damn props in the world if you do, like jesus) then we'll simply have two versions to cherish and keep around on our hard drives.
tl;dr
Don't get discouraged. People, including me, don't intend to be mean or to start anything. We're just passionate about one of the oldest and most beloved games of our hentai careers, so of course we want to be a part of and discuss things when it's brought back to life! We won't agree with every decision you make, and that's okay, just as it's okay for you to stand by your decisions.
