A fair few elderly bugs were squashed at the same time. Did you know that once in every 256 games or so, you'd get NO enemies? Did you? Fixed. Also, the 'where did the 10 second time upgrade go?' question has been resolved. It was down the back of the sofa. It has now been returned, 'eeping' and wriggling in protest, allowing preposterously long games once more.
The leaderboard has also been reset, so happy bouncing!
