Hi! No at the moment, this tool actually is more like a plus for the assets pack that turned have potential to do 8bits,etc... but too "prototype" to sell as standalone and give support.
I have problems with Linux/mac that only can load images via URL,etc... so if i can solve most of the problems and give a good version will be released separately, but now is like that, adding options just for fun :P
Maybe when i get something more stable i will post a poll or something talking about the limits and showing exactly what you can do and their results and see if people is ok paying of it and do a research about how much.
