Pros

1. Simple to play
2. Lot’s of different types of towers to build!
3. Cute graphics
4. Good to play when you need to waste some spare time
5. It’s universal app

Cons

1. It’s currently priced at $2.99, I got it during a promotional period but now it’s a little pricy
2. Some of the levels does look repetitive but still fun
3. Not all the towers are available for all maps/levels so it’s less difficult to make a mistake (This probably true for beginning levels)
4. The endless level are not available in the beginning so I need to complete the adventure mode first I guess! 😀
