Description
A native Android port of Hollow Knight (GOG/Steam, v1.5.12620 "Voidheart") built for the AYN Thor dual-screen handheld, in the spirit of the PS Vita port. It is a same-version Unity rebuild that you provision from your own copy of the game — no PC step needed, the patch applier is compiled into the APK.
The bottom screen shows a live HUD (masks, soul vessel, geo) mirrored from the game, plus touch-driven companion panes that keep running while you play: a live quick-map with "you are here" compass, pinch-zoom and drag-pan, an inventory with item descriptions and controller glyphs, and a full charms grid with equipped row and notch count. Story overlays — tutorials, lore tablets, NPC dialogue, item popups — render on the bottom panel, and room transitions, deaths and cutscene fades sync 1:1 on both screens.
It also supports plug-and-play controllers with automatic button glyphs, touch controls when no gamepad is present, rumble, 120 fps, CustomKnight-format skins, and an optional mod menu with quality-of-life toggles and cheats.
