Tiki Towers is getting quite good actually. I don't really think about the physics but it's good fun. I found it a bit annoying until they released an update allowing you to scroll around the screen, so I'd definitely recommend it.

I wasn't sure about Brothers in Arms but decided to buy it anyway. Haven't regretted it AT ALL! It's very good, admittedly, the controls take a while to get used to but not as long as some of the reviews suggest (car is the hardest to control). There are three different interesting campaigns (all of which I've completed as it's not overly hard!). I would definitely recommend it!
