Its beautifully designed, game play itself is wonderful. It stays relaxing yet engages you into its little world. I would have given it 5 stars except I found myself suddenly struck with the realization that this game has an agenda, and its very anti-mankind. Each section of levels represents a period of time over an evolution-based timescale. In the beginning its the "happiest" with just plants and landscape. The next level, the music gets more ominous and we are introduced to a new character: the red dot. These dots represent the "death brought by mankind." After this, he landscape forces plants into increasingly more difficult places to grow and its matches by an increasingly more industrial background each time. In the end, the red death evolves into streams of lava-like death emanating from the industrial high rises themselves. ***But wait, theres more!*** The trees themselves arent just "plants," they represent evolutionary "family trees" of animals. They touch the red death of humanity and they die... (get it?) cause mankind kills EVERYTHING IT TOUCHES!!! And yet the family trees themselves grow when pruned, because as branches of it are pruned off, the given environment can hold more of the existing types of animals and they can "evolve" further (ecology in a much-stunted nutshell.) Soooo like my title says, it boils down to a beautiful allegory of how mankind kill everything and they are the scourge of evolution that messes up everything. Yeah... a game with an agenda indeed.
