I think this person might have been referring to the fact that the UI is not scaled to the playable window, so the UI overflows the screen and you can't get to click the Start Game button on the explanation window.
I'm a web dev, so I've manipulated the page to be able to play the game, but most other people won't know (or care) to do that.
Making the UI scale to the window is something to work on next time, though!
