School of nightmares frustration

Anyone else get kind of frustrated around this point in the game? It was long but honestly I didn’t mind that much until the end. I just don’t understand how we lose and Kieran and Clear win. I have nothing against having the mc lose when it makes sense. For example valor mountain was such a great loss because we are clearly on the back foot and walking into a trap, and because of our recklessness characters die. In this case however, between all of us and the puppet master how don’t we beat them. Puppet master was so powerful he was going to rewrite reality after we let them get away. Like we could literally just jump them lol. I know I’m so close to the end and I put in so many hours but I’m kinda losing motivation to finish the game. I feel bad too cause the game is so good. Idk I’m probably just overreacting.
