Stack bars as high as you can. Time your taps perfectly to keep the tower alive. Unlock hidden modes. Climb the leaderboards. Tap. Stack. Climb. A bar slides across the screen. Tap to drop it. Land it clean and your stack grows. Miss the edge and your bar gets shorter. Drop it too far and you lose a life. Simple rules. Tight timing. One screw-up away from disaster. FEATURES - One-tap gameplay the whole game lives in your thumb - Perfect landings grow your bar back and feel incredible - Rare multiplier tiles appear deep in runs 2x, 3x, 5x, 10x your score - 3 difficulty modes with hidden unlocks - Game Center leaderboards for each mode - Dark and light themes - Haptic feedback on every landing - Offline. No account needed. No sign-up. Hidden Modes: The menu bars hide two unlockable modes. Figure out the pattern. Once you unlock Insane, you've earned it one miss and you're done. Remove Ads: Short interstitial after each run. $0.99 one-time purchase removes all ads forever. That's it. No subscriptions, no tiers, no gimmicks. About HAHAHA Games: StackUp is the third game in the HAHAHA Games series small, sharp, hyper-casual games built solo. Check out TapTrap and StickCatch while you're at it. hahaha.dev
