Not a single * & about 8 new points per iteration (hence, less iterations). May overdraw, however.

For Friday brainfarts (I saw the bad version to often lately, even in my own code)

instead of
Code: function isLegit() { if(_legit === "katze") return true; else return false; }


do
Code: function isLegit() { return (isLegit === "katze") }

Whoops missed the underscore in the good version
