I'm sorry that the game causes you to feel that way. I'm also playing NMS (No Man's Sky) at the moment. When I began to fly, I experienced some disorientation but the disorientation subsided after 5 to 10 minutes of learning flight control. I found the controls in general to be quite strange and unfamiliar at first, but now that I'm accustomed to them, I appreciate their design and consideration. It's apparent to me that Hello Games wanted to create something unique unlike anything other game.
After thirty hours of play time, I'm firmly enthralled in the experience and beauty of NMS. I'm still learning about the game after all this time. Beware! The more you know, the more addicted you might become.
