Latest version on Linux appears to be lacking the video cutscenes, instead just showing a completely white screen until I hit the space bar. Reverted to version 1 and the videos played fine, so something went wrong between versions, it seems.
Thanks for letting us know about this - we don't have a Linux station to test on, so it's largely been a test of faith. We did upgrade Unity versions between releases and that unfortunately messed with lighting as well.
