This is pretty much in competition to Fallguys thread, but a little competition now and then is a healthy thing
And anyway, they're somewhat dissimilar game types.
I'm going to take this opportunity to re-mention

Some background: the mod version of the game won $50,000 and two engine licences from the Make Something Unreal contest, and the devs have had going on eight months to build a really incredible game, from what we've heard on the forums. The changelog apparently runs over a hundred pages
Primary release of the game is going to be over steam, and there will be a box version in stores. Release date is sometime in march.
