Hello! Thank you to you for taking the time to reply in details :-) I'm also glad my feedback didn't upset you... I was honest, but it doesn't mean I'm right or that changes are needed 😅 Criticizing is so easy but making a game is a very long process.
I also loved games like Monkey island and the fact that I got frustrated is probably because I haven't played this kind of game for a long time, so I'm a bit rusty and impatient, especially when now on more "official games", you always find the complete solution online when you're stuck. That said, having kind of subtle "hint" mechanism could be a way to let less experienced players progress rather than get stuck and give up. This could either be a text hint, or even something displayed on the map to indicate a place you may want to check out to make progress.
The thing about the fires/candles is a good way to know what has been visited indeed and I hadn't seen the smoke until you mentioned it 😅
With the info you gave me, I should be able to move forward and hopefully see the end of the game. I will let you know when I play again! Cheers
