When launching the game from GOG Galaxy it opens a small window in the middle of my screen, and all of the menu's do not appear to be in english. I tried to see what I can adjust from the settings option in GOG Galaxy (no game settings) and can't figure out what to do outside of that. I am running Windows 10 64 bit with an i7 processor on an Nvidia 1080 graphics card if that helps. I appreciate any recommendations!

Language option is 2nd from the bottom, just click on it a few times until it switches to English. Game launching in a small window only happens until you change default settings for whatever resolution you're comfortable with. Dev acknowledged that and will try to fix it, so game will automatically detect your screens resolution.

Thanks for posting. Was having same issue with game launching in small window. This solved it.
