I'll give it a go. I believe there are a couple of reasons for it:
First one is because this game was stop after several updates, then completely started over. In the first round of it, it got a lot of flack because Adele got raped in one of the paths. A restart was actually a good thing for this game, but it still sours it for a lot of people. They don't want to invest into something, only for it to be completely started over months later. I completely understand why he restarted it, with the raping of your sister, turned away potential patreon's. Also, his dev skills had increased considerably by that point, so why not start over and use those new skills from the get go!
Second, is the first free roam at the house that everyone gets stuck at. First time I played the remake and got to that point, I couldn't figure it out at all. So I closed the game and deleted it. A few months later I saw it under the Latest Updates, downloaded it again, started it, loaded last save, and then remembered why I stopped there. This time though, I came to this thread and saw how to get past it. After that, I was impressed with how the game progressed. Adele no longer got raped, due to the kidnapper having his rod cut off. In fact, I liked it so much, I became a patreon! But I would imagine a large amount of people who try this game for the first time get to the free roam part, can't figure out how to proceed, can't be bothered to research how to proceed, then simply delete it and move on. Not realizing how good of a game it really is.
