From the app listing:
Letris is an addictive game in which you must build words in order to prevent the game board from filling up. Letris tracks your progress over time so you can watch yourself improve. You can also compare yourself with friends with the online leaderboard! Three dictionaries are available: Spanish, French and English!
And it has a new icon! The rough edges are still there, but it's great to see an app as it develops from a neat idea into something that could be very special.
