Were you using the web version?
Json files don't export to html, so the buttons just default to the error text. I unfortunately didn't catch that before exporting.
If you want the menu options in readable text, you can download the game instead (The .json files export with that, so the text is all fine)
A gameplay video will be uploaded within the next day or so. You can also use that as a guide to the text.
Sorry for the inconvenience!
TLDR; Web version didn't export the correct files, so everything is messed up on that build.
