LetterCollapse

First release.
• Tap touching tiles that share a letter and a colour: the group goes, what was above falls, empty columns close up.
• The board is dealt once and only ever empties — nothing refills, so every move shrinks it for good.
• Three modes: Klasik, Geniş, Büyük (classic, wide, large).
• Three undos per game, never more.
• Close the app and come back: your board and score are still there.
• Turkish interface.
• The only network use is anonymous statistics, switchable off in game.
