5380! Not a bad score imo! Fun game, great take on the theme - no idea how you worked out that there is always a solution, but its great to play! I noticed a bug where one of the corners was filled with water when not facing the way that it should have been - but it was the only one that i did see and apart from that it feels very polished. I might be tempted to tone down the screen shake a tad though, as it can become annoying when manically trying to beat the clock!
