A Hollow Doorway is a meditation on the meaningless. A love letter to nothingness and an introspective look at the heart of purposeless infinity. Desperately swipe and spin your doorway in a futile attempt to match the rotation of rapidly approaching concentric walls as sweat pours from your armpits and your soul pours into your trembling thumb. It's fun! - Pretty cool gameplay (it's all right) - 9 levels with an infinite array of difficulty modes - No filler: a veritable infinity of meticulously handcrafted doorways - 10 brand new tracks from JACK+JIM (they're good) - Loot boxes (I'm sorry) - Put a face on your doorway! - An in-app purchase to remove loot boxes from the game (I'm sorry) - Game Center support: 34 achievements & 5 leaderboards - iCloud support - Taptic feedback (iPhone 7 and newer) - iPhone X support
