Excellent work as usual, the game is really starting to shape up nicely. The combat feels quite satisfying and the movement feels smooth. My only real complaint is the lack of new content, as it's still the same single level as all the previous demos with some new tweaks. I'm looking forward to what you can come up with on that front.
As a side note, I think this is the first time the game has worked perfectly on Linux (besides the flickering lock panels) without any tweaking for me, so props for that as well.
