DOOM® CAPTCHA

A CAPTCHA that lets you play DOOM® to prove you're human for educational and entertainment purposes. It uses Emscripten to compile a minimal port of DOOM to WebAssembly, allowing interaction between the game and the CAPTCHA UI.

Participants expressed mixed feelings about the DOOM CAPTCHA, noting its technical creativity but poor usability. One user remarked, "I now suck at playing video games," highlighting the challenge of the gameplay mechanics, particularly the inability to strafe.

Another recurring theme in the discussion was the difficulty level of the CAPTCHA. Another user notes, "It’s been so long since I’ve played doom but without strafing... it’s almost impossible!" This sentiment emphasizes how the game's design may not effectively serve its purpose as a user verification tool.
