This thing is friggin' ridiculous! I picked it up yesterday, and was immediately hooked! Managed to avoid it all day today, though. Until just now -- had another go at "Normal" mode and managed to "win" with 17 lives remaining and 5277 points. No screenshot of the formation, though, cuz I was playing offline, and it locked up when I entered my name at the end.

The formation I used was very simple.. just a few diagonal zig-zags -- maybe 30% of the screen -- with two solid diagonals of level-5 squirters in the mddle.

Damn this is addictive!
