The biggest difference of [Water Fun] to [Aquarium] is the behaviour of separate valleys. The latter requires water level to be exactly the same, even in separate valleys. 
[Water fun] removes this restriction

## [water-fun] Puzzles

#### Four-way set

Would it be possible to handcraft a [Water Fun] puzzle, that could be rotated in all 4 cardinal directions, and every time yield a new puzzle with a unique solution?

The underlying rulset was initially perceived as [Aquarium] but it seems now more correct to include it under [Water fun].
