Thanks for the review, Boston Mendonca. The land isn't being generated. It's already there. It's just being discover (think fog of war). The critters discover land as they move. Also, the buildings have a line of sight of 2 units around them. And hence the land gets discovered when you place them.
As for the installer, Yeah, I can throw a zipped version. I thought an installer would be easier for folks.
I've never worked with music. But my 12 year old is pretty musically inclined. I'll ask him to create some for the game.
Thanks for playing, and rating :)
