I made a game testing your prompting skills

In plain words

This game challenges players to test their ability to craft effective prompts for an AI model. Players compete to construct prompts that elicit desired responses from GPT-4o-mini, with the goal of demonstrating skill in communicating with language models. The game is designed for anyone interested in understanding how prompt engineering works and improving their ability to interact with AI systems.
