The only thing that kept it from being a 10 for me was it's brevity and minimal replay value.

This is probably one of the most gratifying games I've ever played. The primitive polygonal style is evocative of Tron and somehow it doesn't feel cheap, just beautiful. The only problem I had with it is that just when I decided that I wanted to become a Darwinia ninja, to dedicate untold hours of my life to mastering techniques that I had just started to explore, it was over. I was so ready for more. These guys need to keep cranking out new levels like the Times cranks out crossword puzzles - I NEED MORE! Yes, there is a level editor, so some community content is out there, but I have found it to be lacking - none of it really scratches the itch.
