THE EXACT-ZERO UPDATE Every weapon now follows one clear rule: a hit only lands when its Fibonacci damage fits the target's remaining HP, and every kill lands on exactly zero. Single-target, splash, and beam towers all play by the same math. NEW IN 1.1 • Live arithmetic feedback shows how every hit changes a creep's HP • A guided first-session tutorial leads directly into Puzzle 1 • A 34-puzzle Journey with clearer progression; the first 8 puzzles remain free • Hand-painted terrain for Sci-Fi, Fantasy, Military, Retro, Pirates, and Horror • Cleaner onboarding, ad timing, purchase handling, review timing, and privacy controls • Stability and native build improvements throughout Plan the sequence. Watch the numbers fall into place. Finish at exactly zero.

NEW: PUZZLE MODE 34 hand-built levels of pure Fibonacci problem-solving. A fixed budget, every wave shown before it comes, and one perfect solution per board waiting to be found — chase the five-star solve. Each world plays its own set of boards, so every world is a campaign of its own. The first 8 levels are free (for Sci-Fi and Fantasy); one unlock opens all 34 of all themes. NEW: ZECKENDORF MODE The hardest way to play FibDefense. Each Fibonacci value can strike a monster only once, so every kill has to be built from distinct numbers. Your towers respect the math, and they won't take a shot that leaves a monster impossible to finish. 55 lives. No shortcuts. ALSO IN THIS UPDATE - Per-world star progress and level unlocks across all six worlds - Drag to reposition your towers mid-game while the action holds - Wave previews so you can plan before the creeps arrive - A cleaner home screen, level select, and difficulty picker - Audio reliability and stability fixes throughout Thanks for playing. The math is real.

NEW: ZECKENDORF MODE The ultimate difficulty for perfectionists. Each Fibonacci value can hit a monster only once — every kill must be built from different numbers, exactly like the theorem the game is named for. 55 lives. Perfect placement or bust. ALSO NEW - Dark mode is now the default — with a full light/dark appearance toggle in Settings - Reload rings: see each tower's cooldown sweep so you know exactly when it fires next - iOS privacy: the app now asks permission before showing personalized ads FIXES & BALANCE - Smarter towers: they no longer aim at monsters they can't legally hit - Sound effects no longer stack or play late during heavy waves - Projectiles no longer freeze on screen after the final kill of a wave - HUD stats are now clearly visible in dark mode - Zeckendorf economy tuned: gold payouts taper once your treasury overflows — spend to keep earning
