The title says it all. Rktcr demo zero has been unleashed upon the world.
Download it now, while you read the rest of this post. (Zip file contains versions for Windows [32-bit], OSX [10.7+; 64-bit], and Linux [32-bit]. You'll need a decent video card to play.)
This is the first public release of the game, and -- thus -- a great opportunity to provide feedback. I'm very interested in what you, the players, enjoy about the game and what you not-so-enjoy. You can let me know by contacting me directly through e-mail or instant message, by commenting on the game over at Steam Greenlight, or simply by commenting on this news post.
I look forward to hearing about your experiences with Rktcr. Have fun!
