Squid Game

I finished the last season and the ending was disappointing, I liked more at least the part where the baby won but I found it very stupid on the part of Lee Jung-jae (456) not to have pressed the button to start the game before pushing the other player, that is, he had to sacrifice himself after that, and I hated the ending because it implied that the series will continue (I understood it that way) but being played by Americans?? It doesn't match squid game with Americans. Anyway, that's all
