Unlock the Mysteries of the Quantum Realm! Dive into Quantum Cat, a unique 2D puzzle platformer that blends challenging physics-based gameplay with real quantum mechanics concepts. Take control of a cat with the extraordinary ability to exist in multiple states at once! The Observer Effect In this world, being seen changes everything. Navigate through 5 handcrafted levels where "Observers" (cameras and sensors) lock your state. Use your wits to stay hidden, or manipulate their gaze to your advantage. Superposition Mechanic Stuck at a wall? Need to be in two places at once? Activate your Superposition ability! Split your reality to interact with special quantum platforms, dodge traps, and phase through obstacles. But be carefulโ€”your quantum stability is draining fast! Key Features: -Unique Quantum Gameplay: A fresh take on platforming where you control probability, not just movement. -5 Mind-Bending Levels: Progressively difficult puzzles that will test your logic and reflexes. -Stability Management: Collect Quantum Orbs to restore your coherence and aim for the perfect run. -Dynamic Physics: Precise controls and interaction with a world that reacts to your presence. -Clean & Modern Art: A polished aesthetic inspired by the strange beauty of the subatomic world. Are you ready to challenge reality? Download Quantum Cat now and find out if the cat is alive, dead, or winning!

About

Gravity Physics

Features
Read full description

Gravity is a real-time N-body physics simulation of our solar system โ€” fly a spacecraft through accurately modeled orbits, gravity wells, and atmospheres, all rendered in a clean top-down view of the ecliptic plane. Every body uses real physical data: mass, radius, orbital elements, and atmospheric density where applicable. Gravity between all 26 bodies โ€” Sun, planets, major moons, and dwarf planets โ€” is computed live using velocity Verlet integration, so orbits, perturbations, and gravity assists emerge naturally from physics, not scripted paths. FEATURES โ€ข Pilot your own spacecraft โ€” configure engine count, thrust, and mass, then launch from Earth โ€ข True N-body gravity โ€” every body pulls on every other body and on your ship, in real time โ€ข Realistic atmospheric drag and heating โ€” feel the difference between skimming Earth's atmosphere and diving into Venus or Saturn โ€ข Time controls โ€” speed up months of orbital motion or slow down to precision-dock in real time โ€ข Trajectory prediction โ€” see where your current heading will take you before you commit โ€ข Flight trail โ€” trace your path across millions of kilometers โ€ข Extended telemetry โ€” track speed, altitude, gravity, thrust-to-weight ratio, dynamic pressure, hull temperature, time dilation, and more Whether you want to attempt a Hohmann transfer to Mars, slingshot past Jupiter, or just watch the Moon orbit Earth in fast-forward, Gravity gives you a physically accurate sandbox to explore the mechanics of our solar system.

Verdict

The call

Quantum and Gravity Physics are too close to call on the numbers: across 6 compared parameters โ€” price, update cadence, ads and in-app purchases among them โ€” neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
