As a question, are there any currently known issues with the "samus" and the "Mouth full" achievements? I've trying to grind for those several times, and the samus one in particular I know for sure I got well over 50 in one game. But otherwise, its a fantastic game, keep at it!
EDIT: Finally got the Mouth full one, but for the Samus one grand total count is 120 dodge throughs in a row.
