Indeed, my players were not used to certain things that you yourself point out this dungeon requires. Why? Because it was the first time they had ever played. And, of course, you can imagine different solutions to any challenge, even choose not to use it or replace it with another one. But I prefer it when an adventure gives you some ideas.
Do you think differently? Perfect—write a positive review and give it a high score, but allow me the indulgence of having my own opinion about what I like and what doesn’t convince me after 34 years of playing and running games, without needing anyone to explain to me how one is supposedly meant to play a role-playing game.
