This is simply the greatest challenge game I have ever experienced since dark souls, bloodborne, sekiro etc. My challenge is not to die in age 20 to complete the whole game. Anybody can do it. You just have to experience your ways to play. Know your skills. If you complete your first chapter without death and stay age 20, say: "I know kung-fu."
If you complete the WHOLE game WITHOUT death and stay age 20, say: "I still know kung-fu."
Enjoy!!
