Floz: an ounce of water

Shoot down the blobs before the water level rises too much.

Droplets fly slow and are hard to aim, icicles ricochet and pierce multiple blobs in a row, but can one-shot you in the face. The tail can protect against incoming icicles from the back, keep it dry for that. If you got wet, pump the water out and wait for the cooldown to use icicles again. A well-placed shot can take out a whole row of blobs and freeze the waterfall for a while.

Points awarded for low water level at the end of the game and dry tail. You can also earn some by hitting the falling blobs with droplets, but watch out for the waves they produce.
