I have my game Hyper Box up on Steam Greenlight and it is doing fairly well, need a couple hundred more votes to bump it up to a potential release!
I also have a playable early version over on Newgrounds.com and i would love it if i were to have Hyper Box seen on the list
(The early version even made it to the frontpage on Newgrounds and im pretty happy about that, but the first 3000 plays got me about 3 votes on the Greenlight so i guess that strategy didnt work well...)
It is a very challanging and original platformer with a very small game mechanic that makes the player think very differently about how to beat the levels
