Hello Friend.
I want to thank you first for the reasoned feedback. I'm glad you still enjoyed the game, though with some "limitations" :)
For most of the things you mentioned, I'm quite clear, but if you came across the thread in f95zone I'm active in, then you're read that in the near future, I will remake Day 1 and Day 2 completely. I also think the first two updates are pretty ... mediocre :). New scenes and some old ones will be completely re-rendered.
The downside is that, although small, I still have 8-10 subscribers in a SubscribeStar that insist on having regular updates. So the lack of time is key here.
However, if I dare to boast, I would say that day 3 and day 4 are much better than day 1 and day 2. :) Someday if you try them you might be convinced. For now, I only released the beta version of day 4 in f95zone.
