This is one neat game. It's a great casual game, short and replayable whenever you have a spare moment or two. Game play is very easy to understand, but tricky to master.
I thought the leaderboard is a fantastic way to make it comeptitive. But now that I'm no longer #1, I'm not so sure ;)
Will you publish this on the mobile devices? It's looks perfect for that platform.
In all, you've done a sterling job with this game.
