Thank you for the feedback! A fuel limit and faster movement is a great idea - I think this would solve people's main issue with the game. As for the camera, I would have loved to implement this but didn't have enough time. I was thinking of something like the camera follows you but a little slower, so it feels like you're zooming around.
Anyways, thanks again for the feedback and I appreciate you giving the game a second chance.
Edit: Oh, you can't destroy the asteroids, only the aliens. Later on you have to break a shield around them before you can grapple, but I think the games movement is stopping most people from getting that far...
