We have been informed that there is a problem with Giana Sisters videos on Youtube getting tagged with copywrite issues.
We have found what the problem is and are working on taking care of it, hopefully in a few days this will no longer be an issue for anyone anymore.
I´ve made a offical linux statement/post for all the info we have about our linux version that you can find here - http://steamcommunity.com/app/223220/discussions/0/540744936190211502/
This has been a huge request by our community and I will ALSO annouce that a linux version is ALSO planned for Dieselstormers, no eta on that either.
So linux users we havn´t forgotten you, hope you can continue with the amazing patience you have shown us and soon you will be able to play all our games fully linux supported.
