Add RollkofferSimulator iOS SpriteKit arcade game
Complete implementation of a 2D top-down arcade collector game where players control a rolling suitcase through an airport, collecting good dogs and green people while avoiding bad dogs and gray people. Features: - Touch & drag controls for suitcase movement - Automatic scrolling airport floor with tile pattern - 4 entity types: good dogs (small/big), bad dogs, green/gray humans - Spawn system with configurable distribution rates - Collision detection with visual feedback effects - Score tracking with high score persistence - 90-second time limit with 10 dogs + 5 humans goal - 3 lives system with invincibility frames - Menu, Game, GameOver, and Victory scenes - German UI text (Created by Ingo K.) Technical: - iOS 15+ with SpriteKit framework - Modular architecture with Nodes, Managers, Scenes - Physics-based collision detection - UserDefaults for score persistence
