Great shooter but lacks diversity

This is a really good shooter that is a lot of fun to play in the beginning but before long the lack of diversity starts to take its tole. There are only a handful of enemies which only increase in number not tactics or complexity, level designs also only get larger but no new elements are introduced and even though there are multiple buildings to play through the visual design of every level and every building is exactly the same. If they would introduce even a little more diversity it would make this game the go to iPad shooter.
