Cart Life is free/open source
This isn't new news - it happened in march apparently:

But I'd been looking forward to giving Cart Life a spin for a while and it was on my Steam wishlist, then I realised there's no buy button no more, so I looked into it... And discovered the story above - the creator took it off steam and made it free and open source, except he's not put it on "properly" anywhere. But there is a dropbox link:

What a fate for a game that won a bunch of IGF awards in 2013 - not even that long ago :/
