WHAT'S NEW 1. The Chief's check, shown on the board The app already marked a threatened Princess with a red square. It now marks a threatened Chief too. Its square turns blue when lesser pieces threaten it and green when the opposing Chief does, and each threat has its own sound. A threatened Chief or Princess keeps its color for as long as the threat stands, on either player's turn, so a danger left on the board stays in sight. 2. A sound fix If a sound was triggered while the sound effects were still loading, the effects could be lost. They now load reliably. 3. The title page on iPad and smaller iPhones On an iPhones and iPads with shorter screens, the planet on the title page could crowd the title and the menu. It now gives up size so that everything has room. 4. Smoother animation The planet behind the title page and the transition into the demonstration game are now drawn by GPU shaders instead of stacked image layers. They look the same as before but run several times faster on older devices: on a 6th-generation iPad the transition went from about 100 ms a frame to about 30. 5. Finishing touches The crowd sound in the Manator variant now loops without a seam, and a stray shadow along the top edge of Phobos, the moon orbiting Barsoom (Mars), has been removed.
