Man, so geeky, I enjoyed it through, killing the Biter and getting the ultimate treasure :) The only thing that I found weird was that dots above numbers with next/previous bit mechanic. Perhaps you should consider swapping it with just the "n-th bit flip" operation, or something alike. Still, I'd like to see more of that, please carry on the concept. Oh, and I love the pun in the title :)
