Inconsistent style

[luitzenhietkamp]

In Part 4: Tiles in game.cpp I noticed you inconsistently applied your style. To avoid ambiguity you always use this-> to point to member variables. In the Game::loadTiles function you only do this for the first time you set a tileAtlas element.

I really like your tutorial, though sometimes it's a little thin on the explanation. Consider making it in a book.
