I am very glad to get the author's reply. I think the author has understood my meaning about the first and second points. As for the third point, I think I may have been a little rash.
As players will face the challenge of being alone without assistance, unlike before when they would always receive help, their mindset is more anxious. When it's uncertain whether they can escape, it's often difficult to stay calm and think about how to get out (but is this really what you want?). I was concerned that players might force themselves to quit if they couldn't escape, potentially losing progress due to the lack of saved games. However, this could be avoided if players were more cautious, so I was being too hasty.
Ultimately, it's due to the lack of clear rules. Despite meeting the requirements for 9,000 people, the game still fails to meet expectations. The more frustrated one becomes, the harder it is to stay calm. I believe that after optimization, the gaming experience will be much more enjoyable. Thank you for your efforts, author.
