There's a visual bug where you can hide pieces of the 'e' behind the completed portions of the 'e' - it doesn't work for other letters because they still show the outline.
Enjoy this for the next 10 minutes, because it's about to be gone. Thanks for the bug report!
Hm, good point. Thanks!
It's very fun to troll other players with, especially that middle bar piece is easy to hide. I've also seen someone play keep-away with the last piece. Just overall very funny how much you can goof off with a simple puzzle!
