Can't help but geek out over the puzzle-boss interplay in 'Lies of P'—the way the riddles are woven into the environment is so clever. In my experience, the riddles that can open routes to secret boss rewards aren't flat trivia; they reward thematic thinking. For example, when a riddle mentions gears, metal teeth, or ticking, the correct selection tends to be a mechanical word like 'clockwork' or 'gear'. Choosing a musical or lullaby-themed option when the clue references song or silence often opens up hidden paths or triggers an optional encounter. Likewise, riddles that invoke family, strings, or puppetry usually want a choice like 'child' or 'string', which can cause NPC behaviour to change and sometimes spawn tougher optional fights.
I also learned to read the environment: oil stains, stage props, or toys near the riddle pedestal point towards the right selection. Solving these with the thematic selection commonly drops unique upgrade parts, alternate boss rewards, or opens a door to an optional arena. It’s less about memorizing a list and more about matching mood to word — still, the recurring safe picks I hit that produced secret rewards were words along the lines of 'gear', 'lullaby', 'memory', and 'string'. That little pattern saved me more than once, and I walked away with some neat extras and a grin.
