I looove the art (and I love penguins...). Like the rest I got confused on the gameplay since I couldn't really get when I was making points or not. At some point I got sad watching my penguins burning in ashes, I decided to stop the torture. Maybe a tutorial level would help a lot to get the idea of the game with just one penguin or two. At the moment I got a bit confused and kept hitting my keyboard to save those poor birds.
I love the idea though! I really hope you can tweak it a little because that's really a nice game! Great work!
