I can't believe you're able to play at those speeds!!! That's so good. As for the difficulty after scoring 1000 points, you're right, the number of crates was calculated using the rolled over score instead of the actual total score which is why the amount of crates went down after the score rolled over. I've fixed it now and uploaded the patch :) Thanks for letting me know (although I don't think anyone else who scores over 1000 will be thanking you ;)
