There is some rabid interest in the game from a small group of people. The pre-orders started before it appeared in Kickstarter, and the game is coming out whether they got some arbitrary amount of money from Kickstarter or not, as it seems to be mostly finished from what's been posted by the developer. I think Kickstarter just provided a more visible way of getting pre-orders when compared to their website.
I pre-ordered the game before it went on Kickstarter, so I've been playing the tech demo. It's fun: very nice detailed deformation, decent arcade handling and physics. Check out my gameplay video
. Personally, I'm really looking forward to the beta.
