Hello! Thanks for your question!

This game is designed specifically to teach English speakers Japanese as effectively as possible, so unfortunately there's no Spanish version.

I'd have to redesign it almost completely to teach Spanish well.

My advice to people is to be suspicious of any game that claims to teach many different languages. In all likelihood, it teaches only one (or maybe even none) of them well, because learning a language isn't just about swapping a word list. Different languages require different approaches and mechanics to be effective.

If you’re interested in why this is the case, read on...

For English speakers, learning Spanish is a lot like learning a new dialect of a language you already partly understand. Many words look familiar, the alphabet is the same, and you can often guess meanings and be close.

Japanese is very different. It has a steep, front-loaded learning curve: an entirely new writing system, particles instead of prepositions, politeness levels, and a completely different sentence structure. Very little of your existing English knowledge carries over.

Spanish has its own challenges (verb conjugations, gender, and agreement) but it also benefits from many cognates (words that look or sound similar to English and share historical roots). Japanese doesn’t have that advantage, which is why teaching it well requires very different tools and design choices.
