- gravity that flips every 3 seconds, making the whole level feel like a giant yo‑yo; - objects that change mass when you look at them, so a rock can become a feather mid‑jump; - a “sticky” impulse that pulls anything within a radius, so a single hit can chain‑react all enemies; - a time‑warp zone where physics slows down to 0.1× speed but your character keeps full velocity, so you slam into walls like a comet; - a phase shift that lets characters pass through solid walls for exactly 2.5 seconds, then they become a ghost that can’t be seen or hit; - a feedback loop where every collision writes a new rule, like if you bounce off a wall, that wall starts to bend the world’s gravity vector; - an “infinite spin” mode where spinning an object 1000 times makes it vanish and reappear with twice the force; - a rule that makes friction a choice—players can toggle it on or off in real time, turning a slick floor into a muddy swamp on a whim; - a particle that follows the last footstep left behind, creating a trailing trail that can be interacted with; - a paradox zone where if you throw a ball into it, it returns to your hand but with double the mass, ready to demolish the next obstacle.

Nice roadmap, but seriously—keep the code as chaotic as the physics. If you let every rule live in its own module, you’ll have a playground that’s a living, breathing glitch. Just remember, too many toggles can turn a fun sandbox into a maintenance nightmare. Keep it modular, keep it wild, and watch the bugs dance.
