NeonSwipe DX vs Crazy Climb Physics

NeonSwipe is a SpriteKit-based cyberpunk arcade snake featuring pure swipe controls and 30 progressive stages across 5 distinct worlds. ARCHITECTURE - Engine: SpriteKit with tick-interpolated motion at 60 fps - Controls: UISwipeGestureRecognizer (4 directions) — zero on-screen controls - Persistence: UserDefaults JSON-encoded GameProgress struct - Target: iPhone portrait only, iOS 17.0 minimum STAGE DESIGN - 30 stages: 5 worlds x 6 stages each - Worlds 1-2: Pure food-eating snake core - World 3: Obstacle blocks added procedurally - World 4: Mixed obstacles + increased food goal - World 5: Chasing AI enemy nodes (pathfinding via SKAction sequences) - World 6: Stationary turret nodes firing bullet projectiles SNAKE FORMS - 6 unique forms, one unlocked per world - Each form: distinct base color + particle emitter trail - Form selection persists across sessions SCORING - Per-stage star rating (1-3) based on score threshold - Best score and best time tracked independently - Stage clear flag persists indefinitely COMPLIANCE - Zero network calls, zero permissions - No IAP, no CloudKit, no App Groups - No third-party SDKs or analytics

CRAZY CLIMB is a pro-grade climbing simulator built for enthusiasts. (Core Mechanics) * Real physics: SpriteKit engine models gravity (9.8 m/s2), friction, and grip stability * Distinct mechanics: 6 hold types (jug, crimp, sloper, pinch, pocket, volume) with unique stability parameters * Calibrated curve: 15 levels from V0 to V8, route density and complexity progress measurably (Data Tracking) * Wins / falls / free-climb peak height tracked in real time * 36+ achievements: first summits, streaks, height milestones, technique mastery * Profile dashboard at a glance (Design Principles) * Minimalist flat UI, zero visual noise * Fully offline, instant play * No ads, IAP, accounts, or data collection Built for real climbers. Friendly for beginners.
