The touch controls for the Alpha 3 port are usually simplified compared to the full mobile release. Expect a floating joystick on the left and context-sensitive buttons on the right (Jump, Interact, Crouch). It takes some getting used to, but it functions well enough for a slow-paced stealth game.
Search for "Hello Neighbor Alpha 3 Android" on Google or directly within the GameJolt search bar. You are looking for pages hosted by reputable community members (often names like Uaz or other porting groups appear in the credits).
Since this is an unofficial game, it will not be on the Google Play Store. You have to install it manually.
The build took place entirely at night, emphasizing a darker atmosphere.
