The third room's sheer dumb luck-based solution is evaluated a few days later, where they conclude that there was an alternate, much simpler or perhaps more crude method, which they never got to figure out because of a participant's affinity with the "enemies".

First room they survive through because teenager was too adicted to League of legends and ignores the corrupted family the entire time. Everybody else died.

Second room they only survived because 2 NPCs were actualy hostage paranormal agents with high mental resistance and could break the hotel's control for short amounts of time, hence, giving the MC all the answers. Everyone else died, again.

Third room they become farm animals and only survive because one of the characters has affinity gift/cheat and tames the cthulu like entity, while everyone is sucking their own thumbs or making dumb decisions. Need I say more about a bunch on dumb deaths by the rest?

First: There's a limit of 4 clearances per room. Hence why they can't repeat each room.

Sure, good reason, if it's true, but the novel didn't have that information before chapter 70, nor the characters knew that information before plunging into each new room unprepared and barely surviving the last one through sheer luck and overwhelming amount of deaths. For me to not call them dumb, they would have to have tried the first room again and the hotel warn them of the 4x rule, just like the hotel warned them that not challenging rooms would be met with dangerous encounters, like the pool monster. Also, the hotel had already warned them about a treasure in each room, which would be a proper reason for them to repeat it, aside from extra safety of challenging a known room.

Second: The MC wasn't given the answers at the second room.

They were in a haunted mansion. The Buttler and his assistant were paranormal agents disguised as NPCs. Both of them broke mind control and told the MC that the answer was in the old church. He just found that they meant the bell atop the church, which was used to solve the plot. The buttler found excuses to brind them there and even disapeared for hours to force the characters to investigate. The girl literally broke control and called one of the characters and idiot who was going to die and went to the basement to meet the 'devil' of the mansion at the end after talking with the MC about the entire plot. The buttler would have killed the MC because the NPC he was playing as was one of the culprits, but he broke control and jumped of a cliff instead of killing the MC.

Third: The goal of the third room was just to survive the farmers and the cthulu-like entity that according to the reviewer was an escaped convict.

Each character became and animal and would either be butchered by the farmers or the entity. They could talk because a new character had a chat group skill, which was too convenient, and the entity kept saving a character who became a duck, because she has the tame skill. There were no clues about the mission/reason for that room, which brings back to my critic of lack of foretelling or clues in each mystery. The characters are just moving aroung in the dark and end up winning by luck / plot armor. The third room was by far, the worst, and the one who made me drop the novel.

Fourth: the rooms are trials and each abitily a key to pass the trial. The hotel is actually a tower of trials.

There were clues to this fact, so unlike the 4 tries per room complaint, this is a proper point. But it doesn't contradict my complaint of: Characters should be more than their magical gimmick. They should surpass challenges using their wit, strength or values. Having a room being a lock and a magical skill being the direct key is boring and bad writing. Luffy from one piece is a great character because not only he finds new ways to use an allegedly bellow average skill and brawl with stronger ability users, but also has a determined personality who refuses to back down in face of greater powers. That's how he solved several plots points in One Piece, by courage in face of adversity and wit while using his rubber powers. Here the characters are so useless they barely explore their own powers and use them without knowing, like the girl in the third room, who was the target of "You could change her for a potato with the gift and the result would be the same".

So That's it for the defense. Hope it can solve any doubts. But if you still think his points has any seamblance of reason, just read the novel. That's the best way to solve any doubts! Cheers and happy reading!

For example when they exit de room 101 instead of confronting the mistake they just shut up and ignore it? I can't undestarnd how they can gloss over something as important as that, moreover they are suposed to get things when completing a room but the autor didn't metion anything? Do they need to survive all ? I don't know because I'm already thinking of dropping this.

There is also the point of going to the reacreation zone, the basement, an instead of looking carefully around it you just go on your own way? Are they nuts? Even more gravely is the mistake of not paying atention to the hotel notifications, it's like the author just want to make the situation worse on purpose.
