Interesting proposal, but your version will have pics and animations with something different? (Exclusive)
Or is the focus just script.rpy (narrative ..)?
Dev chose to prioritize the story in more detail (and more dialogue)
Unfortunately it is quite complicated in certain languages to literally change to English.
Worse when the translator chokes, and you don't know that you are grammatically correct or if the text is 100% coherent.
My native language is also not English ..
When in doubt between my text in English and google translator I flip coin
...
Unfortunately a lot of people take grammatical errors very seriously ...( in trivial situations ..)
Now, if the intention of the Dev is to have your game on Steam ....
Anyway, if your help speed up the updates and motivate the Dev to continue, it will make a big difference.
Thanks
