Great game.
A semi-challenging, original puzzle game. It's pretty decent, although it seemed a tad easier in parts, since I was able to use the same idea over and over to get the puzzles done quickly. Even then, if I made one mistake, I could quickly trace it and correct it.
I'm going to suggest you put a move limit, to give it that extra push. As well, try to develop some really difficult levels. The last one is a good example of difficult. If you had added other overflow pipes to confuse the player, it would've been a killer stage.
