5 stars from me on this. You've smashed it in so many ways considering the amount of time you had.
Nice and eerie, and I felt drawn in to the story. This one has an instant appeal. The movement is just right as well for me.
I'd say the inventory system needs some work. As it's a bit confusing how to move things around. But I totally get why that would be given the amount of time you have to put everything together!
That maze on the red planet was a bit dark.
Overall though. What a really good game. VERY WELL DONE!
