I've whined a bit already about early access, but this news story is kind of a big deal on the discussion; The Stomping Land was removed from steam store.
Steam are under no legal obligations to refund people (link). You are buying the incomplete version, not a promise of the final version. Its not a pre-order.
If cookie dough is selling for a higher price than cookies, why would anyone sell cookies. 5 people on kickstarter payed more than $400 for this game.
The saddest thing is; this game had potential. And now it will probably never be made properly. You can't wholly blame the developers, the consumers aren't incentivising them to bake.
