The major changes and that not enough work design of the graphical classes resulted in that the different graphical classes couldn't be implemented on their own. Instead changes often had to take place in many different classes when some feature was added. This made the implementation slow, especially in the beginning, since there where many different ideas on how things should be implemented. This got better through time though, when the basic foundation was implemented it got easier to add the rest of the features.
