With all due respect, I disagree with you. The intent of creating a playable application, let it be demo or a full version is to consider the outside perspective. People should not and won't play the game the way "you want". If 1 person out of 10 finds the same path, that means just that. Sorry, but you are making the general players feel guilt and frustration and defending your game as if they "should" play it the way you want. Sorry, but no. When I make games I always consider that some players might walk or run or do that and this. It is a big mistake. Watching other people play can improve your development unless you are willing to face the criticism and be humble.
It is your choice, do what you want, but if the marketing of the game is "monster too fast and hard to complete" they won't come back for more. And just because 1-2 people out of 40-50 play the game as you say "correct", means nothing.
Good Luck.
