Ah, I see - I did once have the option to import translated language files in-game when I was working with someone for an official Spanish translation - but that fell through. The process of translating it shouldn't be too difficult, but it's not something that I can currently dedicate time to supporting myself - sorry about that :(
I have considered Steam, but I think it'd be an option when he game is in a much more complete state. Maybe once the game is fully finished, I could try and upload it there? Otherwise, I have my Patreon and Subscibestar which are currently helping fund continual development, so I'm pretty happy :))
