I liked it a lot! I like astronomy, and The Martian is one of my favorite books, so I liked the concept a lot. The camera was BUGGIN" for me though. When not in the telescope it was incredibly stuttery and hard for me to control, almost as if it didn't want to move. Telescope was fine, though. And I love the detail that the telescope actually moves when you look around, and is left off pointing in whichever direction you left it in!
