This could've been done better. A whole lot of hype was built up at the start to what became a mediocre game at best. There were only two "types" of enemies that popped up at all. And only one functional level. On top of that half of the menu features didn't do anything at all.
When playing I felt that some of the targets were a bit small and since they were static, you couldn't notice them that well on the background. You could've added more features such as power ups, or health instead of the awkward lives features.
