Game was great while it was working, beat one map, went to another, then the game started to make this god awful sound, like all the sounds in the game playing at once. Not sure why it did that or if any one else had this bug.
Game is pretty fun, but as others have stated a bit repetitive, but I was looking more at the aspect of the game as a space age space ship shooter, and that's what it is. So no reason but to give it 5/5 since it fits the cut pretty well.
