Wow! In 2016, to have a successful Kickstarter, you don't even need to deliver anything; you just have to be charismatic and write interesting updates for people to want to give you money.
What else do game makers do than deliver dreams? Just maybe not the dreams you planned on delivering from the start. :) Grats on your successes, may they grow with you.
I backed this from the beginning without the expectation of getting a real game - but rather backing research into voxel tech that up to then was mostly a cool tech-demo. I think the initial kickstarter was also pretty clear about this only "possibly" becoming a game eventually. It being released as opensource is something I had hopes for, but never expected - so for me, this is indeed a successful kickstarter. I've had others that supposedly were successful - but which in my eyes completely failed to deliver (hello Ouya).
