Ball rolling(2D) vs Gravity Runner

A simple ball rolling game (hold down to display trajectory)

Gravity Runner — defy the laws of physics! Are you ready to challenge gravity itself? In Gravity Runner, you control a fearless cube hurtling through a neon-lit corridor. One tap flips gravity — sending you soaring to the ceiling or crashing back to the ground. Time your flips perfectly to dodge deadly obstacles and collect shiny coins along the way! SIMPLE TO LEARN, IMPOSSIBLE TO MASTER One-tap controls make it easy to pick up, but the ever-increasing speed and tighter obstacle gaps will push your reflexes to the absolute limit. How far can you go? CORE GAMEPLAY • Tap anywhere to flip gravity instantly • Dodge red obstacles that come from above and below • Collect golden coins scattered through the corridor • Beat your high score and challenge yourself to go further every run POWERFUL BOOSTERS Gain the edge with three game-changing power-ups: • Shield — absorb one hit and destroy the obstacle on impact • Magnet — automatically attracts nearby coins for 10 seconds • x2 Score — double all points earned for 30 seconds UNIQUE SKINS Express yourself with 5 unlockable player skins, each with its own glow, trail color, and particle effects: • Default Green — the classic neon runner • Fire — blaze through with orange flames • Ice — cool blue with a frosty trail • Shadow — dark purple stealth mode • Gold — the ultimate flex for coin masters PROGRESSIVE DIFFICULTY The game starts smooth but ramps up over time — obstacles get taller, gaps get narrower, and speed increases.
