#13 I like the emblem design a lot, the tetris thing is nice, good colors too. The namespace "PlayLark" doesn't do it for me though. Its a little blah, maybe it's the font - it's too blocky or clunky.
Basically #13 the name-space "Playlark" could be more feminine - since that'ss 65% of my target market. Also, it'll be cool to see the L not capitalized.
#13 - Where the green is, can we make that blue and where the blue is can we make that green? I like this, but I definitely think the Playlark part should be softer and more friendly.
