I like how pepole are saying "Ooh Yogscast stole the money and ran away! I know nothing about this because I've done no research so I'll just complain because I'm a keyboard warrior!"
Winterkewl is solely responsible for this - Yogscast only allowed them to use their brand, they are completely independent of each other.
1) People wanting refunds can get in touch with Winterkewl.
2) Yogscast took over the assets and handed them over to Nerd Kingdom, developers of TUG, and Yogscast are now giving out free Steam keys for the the game so that folk are still getting a game, with some of the assets.
3) They made good on physical Kickstarter rewards, and the digital rewards will be replicated in TUG.
Seems to me the Yogscast are trying to make an effort even after Winterkewl failed to deliver.
(inb4 someone whines about them trying to claw back fans or something.)
