I did 1,075,100 (died on round 8, 1264 evil toys broken) on my last run.
After I got that the efficient way to stay afloat was to shoot batteries then the game flowed pretty well.
The game is excellent, it looks and sounds great and I had ton of fun playing it. The speed of things and difficulty are perfect, you've quite some bullet patterns there and the more you advance the more intense it gets.
Very strong entry, I love it.
