The bugs are intentional.
This game is what it would feel like if you got mind screwed by Total Recall.
Are you really sure about that ? Let's take the first bug that anyone will encounter, the inventory. It's a link displayed on the main screen which lead to a crash because the image don't exist. Or the fact that you see a character twice in the same screen because the author forgot to hide the previous picture ? Or the fact that you suddenly see a character that isn't even in this location and say absolutely nothing (well, this one why not) ? Or the fact that in the middle of a scene, the background change from, let's say your room to the facade of one of the house ?
I agree that there's perhaps few things that are intentional and intend to visually display the PTS of the main character, but sorry, most of the bugs are just that, bugs. Or the author really need to learn about PTS and, since the main character isn't completely human now, mental issues like schizophrenia, because it's absolutely not how it work.
This said, I've just had a quick play and a quick look at the code ; wanted first to know if it was still completely broke. I must admit that there's improvements. But like said by
@Infamy, the author really should sit down and take the time to correct everything before adding new content. I think that most of us will still see this as a valid new version even if there's nothing new.
Bonus side for him, a less crappy game can lead to way more patreons, because the idea is good and I think that the author have still a lot to say. In fact I know it. Both his game and code look like he want to go to fast, switching from what he was doing to the idea which just crossed his mind. A little more discipline, and his game can become the next hit.
