i made an account so i could answer this, so i hope this helps, but if you download "NARRENSCHIFF (中文\ENG\한국어).zip" then go to the game options, you will be able to change the language to english!
that's very bizarre! i hope you were able to figure it out and got to play the game in the time between me sending this, but if not, could you shoot me an email? I know this is a bit unconventional but itch will not let me paste the download link in the comments, unless i'm being an idiot and doing it incorrectly. my email is the same as my display name, would hate for you to go without :-)
