Tom Sawyer is my win condition.
I think the new UI is a good idea overall, a bit dispersive since the show is now encircling the board but maybe it's better than switching through tabs.
Buzzwords are a cool idea but I skipped the tutorial and didn't know what they were until I read your post.
There could be a tooltip when hovering over them that tells you what they are.
I still think a log telling you how a particular score was achieved and a word validator checker would go a long way, it sucks to work towards a big word and have it ruined because it turns out that it isn't a word.
