Cool design, lacks a bit of a gameplay loop. Sure, let's grab the screws, but the only threat is the heat and you can abuse it by just dying and going back - definitely make the player lose the screws when they die so it can be challenging. Maybe respirators or cold spots would be a nice add plus a bigger level with a bit more to search for (?)
Not sure what was being learned, but I believe you guys managed to do what you were looking for, so that's pretty nice! The ship and landscape material look cool, I like the style.
