Hey there!
I'd love to be of help to your project but, unfortunately, I don't think I can offer my work as co-writer, as my life as university student takes a lot of my time.
However, if you are interested in getting your work translated to another languages, I am proficient with the European Portuguese and Spanish languages.
I'm more than happy to work for free as well, you can check my portfolio if you feel curious: Liam - itch.io
Best of luck to you! :
