A Hollow Doorway is a meditation on the meaningless. A love letter to existence 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)
- 34 achievements & 5 leaderboards
