all of the puzzles require you to use and fill the overflow pots. It seems like many of the levels could be made to be more interesting if you made it so that you didn't have to fill all of the overflow pots.
Consistently fun, yet difficult, series. Very few flash games play like the old 2D adventure games, where exploration is encouraged and there isn't an obvious path to victory.
