The underwater distortion is especially cool. Here's hoping that some day, you can splash water from one place to another. And that moisture draws upwards grass and dirt blocks to drop like in the image, but not so easily on stone. And that once water has hit that block, it gets a wetness percent that eventually dries out if allowed by the circumstances, drips away or transfers its water downward. Of course, this would be easier for a sequel with higher system requirements.
