Gravity Mass is a minimalist physics puzzle where your touch bends space-time itself. Tap the screen to create a temporary gravitational field that pulls nearby masses off their paths and draws them together. You don’t control the objects directly; you influence them. Pull too hard and chaos emerges. Too weak, and nothing merges. Timing and placement are everything. Each level introduces denser fields, more masses, and increasingly fragile equilibria. Gravity Mass isn’t about speed or reflexes. It’s about reading motion, sensing force, and intervening at the right moment.
