It's disappointing for me too, but I couldn't waste more time on ADGTH, it never got the minimum support and I had to finish it before time, so I can start working in my 2nd project:

Makes me feel bad for people who actually backed ADGTH, rushed endings are the worst. It was a decent and fun little game while it lasted. P-AIH looks... rough, female main protags is definitely a risk (if you nail it, good on you), and the premise of the story seems iffy. But the character models look nice. And if what you said is true, the new coding makes new things easier to implement, good stuff. I hope your writing + patreons ideas, make for some interesting situations.
This choice could also leave a bad taste in the mouths of people who've already backed you, and a small stain on your reputation. I say small stain, because for me personally ADGTH was a decent game, and I think for most who played ADGTH would agree. Showing you probably have what it takes to make something better. Work your ass off man, and good luck. Prove to your backers this was the right choice.
We all have to make choices like this in our lives, good luck on your choice.
