Getting EXC_BAD_ACCESS all the time

[denizs]

First of all - I admire what you've done! The tutorial really helped me get started. However, I'm experiencing some issues while following along:
When I perform a dynamic_case from Node* to Piece* and then try to call piece->getSpriteHeight(), I get a EXC_BAD_ACCESS.

I found this results from the dynamic_cast. Changing the cast to static_cast fixed the issue.
