^Wow i didnt even notice that.
The release that was uploaded to Steam was kind of a "proof of concept" thing. It had 2 (or eventually 3) characters, almost no features, clunky animation, and a single stage.
You can watch the video here... but imagine only two of the characters are playable and none of the promised features. Its just two characters hitting each other... except match making never found me another player to play against... http://store.steampowered.com/app/290810/
It was more like an alpha than a beta, and it never cleared "early access" status on Steam so saying they finalized work on CKC seems very misleading to me.
