Very fun. I'm a big fan of word games, so this is a nice take. A couple of things I've noticed:
1. What I click on doesn't always correspond to what actually gets pressed. It seems that clicking on the middle of a key causes the key directly below it to get pressed.
2. The timed "type as many words as you can" round just straight-up does not accept any words I type in. It doesn't accept the "fill a word out for me" button either.
I have no idea if these are intentional or not, but just figured I'd mention.
