Damn this is a good game. It had pacing, it has upgrading which is always a yes for me. In my opinion there is a way to make the game better. I do feel as if even on the hardest difficulty it was challenging, the fireball does need like a drop on it because I DESTROYED  the boss from miles away and more enemies coming from different directions instead of all clumped up in one side/area.

This is a great game with some excellent graphics of the people being saved.

My only annoyance was that the spaceships would explode unexpectedly. I assume they were hit by an asteroid but it was not always clear.

This is an excellent game. Frustrating in parts but very addictive.
