Very simple yet beautiful looking game which has nice unique settings.
There are some minor drawbacks with the game characters. The main hero is played really well, but the woman scientist (sorry, forgot her name) sometimes acts too cartoonish. That's not how human being sent to a space mission would act. "Ok, you're going to die soon . Btw, wow, that a great slug on a wall, could you get me a sample!" ... ??? - Yeah, sure, but I'm a little busy now trying not to die here, milady. The AI behaviour is kinda childish too, but at least it's AI, you can't blame it for anything, that's how it was programmed!
Nevertheless, it's good. I hope there would be more plot-heavy games like this about "normal" scientists doing cool stuff and exploring alien worlds and not just some brutes with guns kicking asses.
