Many cracked repacks are bundled with trojans designed to steal passwords. These payloads log your keystrokes, scrape saved passwords from your browser, and send them to a command-and-control server. For a game like Life Selector, which might contain personal preferences or saved data, attackers assume you are less likely to report the theft due to the nature of the content.
Before committing, check if the official website offers a demo. Many adult VNs provide the first chapter for free to let you test performance and story quality.
Note that "repack" is not inherently evil. Legitimate repackers like GOG (Good Old Games) provide DRM-free, compressed installers. If you want a small download size, buy the game from GOG if available. You get the convenience of a repack without the malware.
