[Prozac]

How about an upgrade to the level generator:
-snow ground, snow trees, snow mountains, and lava of the same
-varying degrees of cliff heights, cliffs that you cannot jump down from with the darker tiles at the top for mountains and going down to water
-coastline beach tiles between grass and water as an option, to merge with mountain tiles
-path/house placements (to form an outline)
-option to have or not have shadows around the mountain edge tiles over land

and a random thought for gmaps : east and west edge wrapping such that the world would be a vertical cylinder.
