Pretty neat. You guys need a user base. It looks like there was nobody to challenge. But it's fine. Great idea.
Also, a bot may be nice. There are many free English dictionaries. But it may be difficult to balance to get a bot that is not too good but not too bad.
Although we do want to keep the focus on this being a social game. Something you play on discord or at work with people you know. So a bot somewhat takes it away from it.
