Great app BUT...
Its a great app and is teaching physics in a simple and easy to play and understanding way. The abilities are great and it helps a lot to understand fluid dynamics. BUT and this is a big but: the import of png does not work, there are no hints about the dimensions the files should have. There is NO export as png only an obscure wtm file that even Graphic Converter cant read.
So its only three stars. Make the png import and export working and ill give 5 or 6 or 7 or 8 starts
