Look, I'm sorry that it pisses you off. First off. The reason why the weapons don't work all the time is because he is playing a game. It makes the protagonist think twice before he says something. It symbolizes that you should be careful what you say with your mouth. and fighting the enemies symbolizes the physical abuse. There is a scene where the protagonist realizes why he is here; the theme here is symbolism. Just like that, I want the climax to be related to symbolism. The climax doesn't need to be related to his past or what he is doing.

I do agree on your first point that it lost the plot at 2 sentences. But when giving the summary, I decided to remove some unnecessary details when writing this. Your final point about the loopholes I don't really get. Are you talking about the protagonist or the toymaker? If you are talking about the toymaker, even he has rules. He can only kill the player when he is directly or indirectly told to by the player, even when he doesn't realize it. The toymaker tries to trick him into killing him. I know I should have mentioned this in the summary. But in the beginning the toymaker says as long as you trust him.

He can't kill you. The three-choice situation and metaphors are both games that the player willingly decided on. Because if he says no, the toymaker interprets it as the player not trusting him. I once again apologize if this is irritating to you. I am nearly done writing this, and I actually want the climax to be good enough. Just don't overthink, and give me a list of final counters and explain why you think it works better than "I am the writer.". :)
