Ehh... Version 1.4 is kind of broken. The music from the main menu continues to play when you go into a level.
The latest chat message is still pushed halfway out of the screen.
Also, I think the background image is annoying. You should go for something more neutral like a single color.
I'm going to stick to 1.3 until the chat is fixed. Until then, I see no reason to update, aside from getting a flashier main menu.
