very good

this application is very good but with a few more elements and reactions
i have a few suggestions to give
when fire touch plant the best reaction would be to spread inside instead of only burning the particles which touch it
and a few more reactions could be good too
and ice could melt a little all the time letting water drip from it
you could also add an element like wood that could burn real slow and would maintain fire on it
thank you for this very good app
