Plague v3.02 is out

The major change here is the addition of game states (so there is a title screen, help screen, etc) which will pave the way to option screens and scoreboards (and a strategic game state). 

The other neat thing is a "tech demo" where you can see rocks being desposited and my connected set algorithm find the "connected sets" of squares (which is part of why it takes so long to create a level).
