The developers had some technical problems with the Linux port
Humble Bundle 6 is one of the best collection of games released so far by the Humble Bundle initiative, but one of the included games has yet to be released for Linux.Vessel is an interesting title, a combination of a 2D platformer and a physics game. In the world of Vessel, living liquid machines have taken over the world. Their inventor, Arkwright must do everything in his power to stop them.
“Unfortunately, due to some unforeseen issues concerning our Vessel port, these versions aren't quite ready for prime time. We will be getting Vessel out to bundle buyers as soon as possible. We didn't want to remove Vessel from the bundle due to unforeseen porting hiccups, and we hope that you can forgive us for the humble fumble,” said the developers from the Strange Loop Games studio.
The Humble Bundle 6 collection is made up of 10 games: Torchlight, Rochard, Shatter, Space Pirates and Zombies, Vessel, Dustforce, BIT.TRIP RUNNER, Gratuitous Space Battles, Jamestown, and Wizorb.
