i just got an unbeatable run using freeze, next shot bounces, shoot one bullet twice and shoot as many times as it has been played.
also had the bouncing shots pierce perk.
gave me a perma laser beam straight down the middle xD
got to a point where i had 4 free cards which gave me enough time to create and login to an account xD
although this meant that i didnt see what round i got to :(
