I gave up in frustration. I was really liking this game until the "Destroy the Asteroids" section in chapter 4 (of 12). A third of the way through this game. Was a chore and extremely frustrating to try to shoot all the asteroids and survive to continue. Every other section of the game I figured out how to proceed fairly quickly-not here, becomes unfair or ramps up diff way too much after slow shooting gameplay. Almost becomes a different game. This should have been relegated to a "mini game", not a major plot continuance...
