What is nightlight-game-launcher?

Nightlight Game Launcher presents itself in its README as a general purpose Windows application for organizing and launching a personal game library, built with a dark visual theme and described as fast and easy to use. The README states it is meant for launching legally owned games, and the setup process shown is simple: download a zip archive, extract it, run Nightlight.exe, add games to a library, and start playing. The README itself does not describe any technical details about how games are added or launched, what engine or framework was used beyond the C# language shown in the repository metadata, or any source code to review. Its troubleshooting section covers common issues like running as Administrator if the launcher will not start, checking a game's file path if it will not launch, closing background programs if loading is slow, adding the program's folder to antivirus exclusions if it gets flagged, and enabling a DPI scaling override in Windows if the interface looks blurry. However, the repository's own topic tags and short description mention functionality that the README text never explains, including bypassing Rockstar Social Club login requirements, bypassing Epic Online Services checks, offline play for Red Dead Redemption 2, and a Steam account switcher. None of this is described, documented, or shown as source code anywhere in the README, which is a notable gap between what the project claims to be about and what it actually explains. Given that the download is a compiled executable with no visible source code, features referenced only in metadata rather than documentation, and an instruction to exclude the program from antivirus scanning, there is no way to independently verify what the program does once installed. The README lists an MIT license badge but provides no license file link within the text shown.
