This was originally going to be a 100% Pen engine but... Water Physics! This is not perfect, and still very buggy, but I hope you can make use of it. Fell free to use this engine in a project, but please give credit to @Shift-900 › Press 'Space' while holding 'z' to hide/show the variables. › Press 'Space' while holding 'd' to toggle debug (use this if two water droplets are stuck together. This can cause more problems than it fixes though :P ).
