To be honest, I didn't get what was the first game about, even though it looked quite cool. At the second one I asked myself, why the car was disappearing from time to time. I guess it's a function to switch the view. If it is, some comment would be nice (comments within the video in general would be nice). And why only videos? Aren't there any playable demos you could provide?
But else: nice work. Far better than anything else I ever created on a mobile-phone.
