## What is Keepfall?

Two castles. Two cannons. One glowing heart each. Shatter theirs before they shatter yours.

Keepfall is a turn-based castle artillery duel with real physics. Pull back, release, and watch your cannonball arc through the wind into stone walls that crack, topple and crumble brick by brick. Destroy the enemy heart and you win, however much of their castle is still standing.

PULL, AIM, FIRE
• Slingshot controls: pull length sets the power, pull sideways to turn the cannon
• Wind changes every turn, so read the arrow before you shoot
• Hit the gold target for a critical blast, fill the meter and fire a MEGA shot
• Cluster, piercer and homing shots for the moment that counts
• The final shot plays out in slow motion

BUILD YOUR OWN CASTLE
• Stack it brick by brick in 3D: beams, pillars, arches, windows, battlements and roofs
• Wood, stone, ice and iron, each with its own weight and strength
• Test gravity before you save: anything badly supported will fall in battle too
• Hide your heart behind decoys that look exactly like the real one
• Choose a heart type: Living hearts regrow, Aegis hearts raise a shield, Titan hearts are taller and tougher
• Share your castle as a code and challenge friends to break it

MANY WAYS TO PLAY
• Campaign: 12 stages, each with its own castle and twist, and 36 stars to earn
• Four castles: a free-for-all for up to four players
• Gauntlet: castle after castle until yours falls
• Daily Siege: the same castle for everyone, every day, with a leaderboard
• Daily missions, achievements, levels, trophies and leagues
• Play two players on one device, against a nearby player over Wi-Fi or Bluetooth, or online with Game Center

No ads and no data collected. Optional cosmetic extras (castle skins, trails, banners and the Supporter Pack) never change how a match plays. Available in English and Turkish.
