The game is amazing! Art style is nice, story is good and interaction design is well. Can't wait to play the full version.

Speak of, I saw the translate module in the download version of this game, and then I saw a discussion about this in the forum (May 6, 2024), so I want to try to do some translate (since im not a Native English speaker)

However, I didn't find the "Translation folder" or any similar files in my local, so I'm here, trying to figure out where and what I should do to translate

Thank you, glad to hear you liked it. 
There is a little bit more explanation on the Discord, but in short: You must start up the game, go into the translation page in the start menu, and export the current translation first. This will make an english.csv file in the installation folder (raw text spreadsheet, for excel and google docs)
