wtf is jogo-vagabundo-de-ia?

This repository is a single page, browser based detective text adventure game written in Portuguese, called "O Misterio da Rua 52" or "The Mystery of 52nd Street." The author describes it plainly in the README as a very rough, unpolished game, so it should be treated as an early, informal hobby project rather than a finished product. The game puts you in the role of an odd, lazy detective hunting a serial killer known as the Black Killer. It runs entirely inside a single HTML file with its own dark, noir styled visuals: a black background, red and gold accents, a flickering film grain overlay, and a typewriter style monospace font throughout. There is a main menu where you can start the game or open a description and tips panel before playing. Once inside, the game works like a classic text adventure. You type simple commands into an input box, such as examining or looking at an object, picking up an item, moving in a direction, checking your inventory, or looking around a room. The starting room is a police office where you can examine the window, the desk, a cigar, and your boss, each triggering a short written response. Items like brass knuckles and handcuffs can be picked up from the desk, and the game hints that handcuffs matter if you want to arrest rather than kill the antagonist. The game also tracks player health and includes tactical combat, since the tips mention that enemies with a lot of energy need to be weakened before they can be captured. Progress and choices, such as gathering healing items, protective gear, or the handcuffs, appear to shape how the ending plays out, whether that ends in justice or in something more chaotic. Since everything lives in one HTML file with embedded CSS and JavaScript, there is no separate installation step described. Based on the source shown, opening the file in a browser is enough to reach the main menu and start playing. The README marks the current build as a pre beta version, so bugs and rough edges should be expected.
