These concepts may be to difficult to grasp for young players or adults that don’t have the school background covering these topics. As my desire to be true as much as I can to the scientific principles behind making the first contact with aliens, I maintained the science but also introduced tutorials and research sessions with the NPCs in the game. The tutorials should help the player learn about how to use different instruments and tools. I planned a moderate learning curve, helping players gradually face more difficult puzzles as they progress in the game.
