Your brother is right, camera is awful (but making it controllable with a MMB only is even worse), just about everything you needed to interact with can be just done via an Interact button, and the only time you needed a cursor was the puzzle.
Flight controls were really weird, i expected to control the nose with WS and mouse to rotate the camera, instead it's like a flying Warthog.
Decent start, you don't need to play out the animation and the dialogue every time you fail the puzzle.
