Sonic the Hedgehog 4: Episode 1 was considered a letdown by many longtime fans of the series, mostly due to the fact that its physics were not similar enough to the original Genesis titles. Part of the benefit of an episodic series is that developers can listen to concerns such as this and address them in future updates, something quite clearly evidenced in Episode 2. 

This time around, Sonic moves through stages with a sense of weight and momentum far more reminiscent of his earlier platforming adventures, which many will consider a boon. Unfortunately, however, it seems that Sonic Team and Dimps was so focused on fixing that one problem that it forgot to make sure everything else was up to snuff.
