This game is pretty good so far. I loved evidence of life, so I was really happy when I heard about the sequel. There's one thing I think it needs: Scripted events. Maybe the robot could start malfunctioning, or you find the corpse of the first astronuaht and it starts attack you, or maybe you need to use your jetpack in space to fight off against a massive space snake thing.
I love this games visuals and music. It's got a great atmousphere. Well done for making this masterpiece!
