love it! The graphics (beautiful visuals, sands, clothes) give out that Arrakis/Dune vibe.. The fighting system is very dynamic, you can feel the power of your character and it looks professional. After I've finished it i went exploring a bit. Great atmosphere, but I would welcome a bit more difficulty (like risk of dying, not sure if that is possible here). Slight mouse over-sensivity, but it is easy to get used to. (maybe its even better for fast paced fight system?)
Use "E" to press the button next to the ray - i was looking for that in the comments. It took me few minutes to figure it out :-)
