Currently the default word set is entirely french and variable length words, and I haven't implemented a way to change it yet... I'll get to it later...
To play another game, just reload the page! (Another thing I need to actually provide a button for... (It's exam season so you can't blame me for being busy...))
Warning: The Word Set is being pulled from a third-party which I have not fully vetted because it's a few thousand words long (e.g. there could be inappropriate words)
