Congratulations Ashigaru! He finally broke yesterday's game: it was Battlefield 1942. The scribbles were taken from the radio commands at the very top of the UI, where you hit the function keys to issue commands or respond to teammates/the AI.
Well done, mate. But it's a new day, and time for a new scribble.
Good luck! And don't forget, you can email in if you'd like to have people guess your scribbles.
