Nice job! You guys made really outstanding artwork and lighting in this game, it's very impressive. From the ship components to the hologram Mars model to the gruesome discoveries, it was very well done. You also used that art to great effect: the loading dock felt like a loading dock, the break room felt like a break room, etc. That and the sound effects created a very immersive experience, and one that had lots of areas to explore. Nice work!
Some feedback that I hope is helpful: the user interface end of it had a few kinks to work out. The notice that "you have picked up a repair kit" and the keycode pad both got stuck on my screen and I wasn't able to clear them away. I would also be sure that the messages (e.g., the one about Henry) stay on the screen long enough for the user to read them.
But those are easy fixes for a game in which you've already done the hard work of creating a great atmosphere -- nice!
