The primary tool for vibe coding today is Claude Code, but OpenAI has released an alternative product called Codex. I decided to test how it works by generating a game in the style of the classic Mario. Due to the need to use a traditional keyboard, the game is only available in a desktop version and does not run on mobile devices.
The game was created entirely using prompts, without writing a single line of code. The biggest challenge was getting the graphics right.
