Two suggestions: many video game players might not notice that there's a time limit for each day as the sun moves across the screen, so the faster you finish interactions the more people you'll have a chance to sell to and the more profit you stand to make. If you take all day reading everything and asking questions to everybody then the game will be tough to beat, but that will be most people's instinct if they don't realize there's a time limit, and is probably the source of the negative comments about the game being super hard. Just making it clear there's a time limit will probably clue people in and boost the ratings a bit if those people aren't left thinking this is impossibly hard.
The other thing is that there are occasionally gold clouds that float across the screen that you can click on for cash. That's fine during the day when time is moving since it gives people more things to focus on at once, especially if there's a time limit on the day, but I noticed that the gold clouds will still come out when the anvil makes the last comment of the day saying that the day is over if you just wait at that screen without continuing and you can just hang out and click a few gold clouds before ending the day. I'm not sure how I feel about that -- it's cheating, but also would give weaker players a way to make it through the game easily if they don't mind cheating a little and would therefore boost ratings because there are definitely people out there who downrate stuff purely because they can't beat it. So it's up to you if you want limit when the gold clouds can come out.
I had one run where a bug appeared, and this is what I can remember of it. Either day #2 or day #3 (can't remember for sure which) began with no clues about what item people are going to buy a lot of that day, but they seemed to end up mostly wanting swords. I offered to protect the guy who was hiding from the bounty hunter, and on the next day he went through both the dialog thanking me and giving me a bonus for doing so, and I also got a message right after that about needing to watch my back for turning the guy in to the bounty hunter. And on that same day, there were a few times when people finished talking and I had to click the continue button multiple times before it would advance.
The sun also didn't make it all the way across the screen before the day ended on days when I accepted a bonus to have more time during the day -- it made it most of the way across, but not all the way.
