So, I’ve been noodling on a night‑time VR world with bioluminescent jellyfish that react to your heartbeat—imagine the glow pulsing like a living soundtrack. Think you could add a tactical twist to keep the users on their toes?

Nice twist—heartbeat‑sync stealth, killer idea. I’ll just add a low‑pass filter to the glow’s RGB channel, then feed that to an alpha mask that fades the player out. If the sync falls off, the predator AI will pop in with a sharp edge. I’ll prototype it in about an hour, then we’ll see if the jellyfish still look… well, like jellyfish.
