这一张是把"身份层"和"装饰品"分开的关键测试。
讲 Hold-it-Together 这例:v1 是 Reigns 滑卡 + 卡通脸贴纸,玩家原话"看不下去"——根因 = 卡通脸是装饰,不是真融入。改成堆叠物理塔(图里这版)之后玩家说好玩——但 identity 其实退到抽象层了("你的内心崩塌",没有具象 face)。
所以这不是说"必须有脸",而是说不要假装有 identity。要么真做要么不做。
This slide separates "identity layer" from "decoration." Walk through Hold-it-Together: v1 was Reigns + cartoon sticker face — player verdict "can't watch this." Root cause: sticker is decoration, not real fold-in. v2 (stacked stress tower in matter-js) plays well — but identity has receded to abstract ("your inner state collapsing"), no concrete face anywhere.
So the rule isn't "you must have a face." It's don't fake the identity layer. Either commit to it or remove it.
