He give us unique routes for the pig princess and dialogue options with unique outcomes but when it comes to side chicks he gets angry?, there is not good excuse to take away player agency for no good reason, because the reason that you mentioned isn't. I understand that he might feel like all the side content was worthless if some players don't want to see it, but not everyone is into mutant chicken girls or having their buttholes licked by a boar.
I went into this game with no interest in fucking a pig. I wasn't sure about sticking my dick in a chicken in chapter 4 or something. Then when that dommy mommy boar came at me, I too, was shook. But damn was that scene actually pretty hot.
With the countless VNs that make beige seem like a unique and interesting color. Then we have this game, an A tier Furry propaganda with funny, sympathetic and lovable characters.
I too would be pissed if some people were so autistic, they couldn't manage to power through a scene or just skip it with the ctrl button, but, had the audacity to ask the dev to change it for their own weak, beta sensibilities. To essentially cut content that he spent months lovingly crafting.
To quote a great man: "It is not the critic who counts: not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually fucking the pig, actually cumming on the chicken and is balls deep in the boar.
So stop being a baby and write your beta cuck mod to skip the content or build your own princess pig fuck simulator.
