Yup, the game I'm developing currently is coming to Steam! Sure, I make some dodgy little Flash games every so often, but my heart lies with the big games for PC and Xbox 360, so getting onto Steam with this game is a dream come true!
The game is an open world, sandbox type game where you play as asteroids, planets, stars and black holes. More information (plus trailer) on my site: http://murudai.com/2011/03/solar-2-ann ounce/
All the audio (music and sound effects) are from Newgrounds own Rig! http://rig.newgrounds.com/ He loves Steam, so doing all the audio for a Steam game is a dream come true for him :D
