Any plans to release the linux port on steam?

When I try to save my progress, it brings up a window with six black save-squares. If I click on a black-save-square nothing happens. The save square (and all the others) remains black. If I click on the same one again, it asks if I want to overwrite that save and offers Cancel or OK. Clicking OK does nothing (it continues to ask if I want to overwrite). Clicking Cancel closes the "do you want to overwrite" window. I can't load from the black-square that I "saved" to. I tried uninstalling and reinsta...

Will this affect me finishing the level?...
