Is there some way I can get some diagnostics? My solution correctly floods the given example, it correctly floods all of my own tests, and it floods the empty image (which should be the worst case for my algorithm) well within the cycle limit, but the challenge page just says "'failed to flood ...

I can't figure it out. I got the "meaning" column, but people are talking about tools - is that whole encoded thing a red herring maybe?
