I am sure one can have fun with ChatGPT with this prompt. But making a good game out of it to help others learn Toki Pona would be a great challenge. What game engine? What type of game? How to make the story compelling? The game should progressively replace the main language with Toki Pona as the gamer acquires the language skills, at the end there will only Toki Pona, maybe even the game interface will be completely Toki Pona. It will be a fun project to work on :-)
My first assumption was that this wouldn't need to be more than a text adventure, so my first thought was Twine. But LLMs are literally language-based and (near)-infinitely flexible, and many already are capable of Toki Pona. There are some incredibly elaborate LLM games driven by a single prompt.
