I don't know if anyone has heard of it yet, but I saw it on steam and it's free. (not released on steam, yet) DL from site.
http://www.dyson-game.com/It's a simple strategy game. You have these plant/spaceship things that float along a planet and you can grow more plant/spaceship things. You can choose what to grow such as offensive or defensive plants. You raid other planets and grow armies of these things. Everything is explained on the website. The music is very soothing and everything looks "stylish."
Try it.
