I can describe this in a way as bad as it can be or as good as it can be. The bad part is at first you don't know what to do or what is happening or even while you die. Well the object is simple, get past levels until the game is over, however, people bump into you causing your stress meter to increase. Once it completely increases you become Hyde, while you are Hyde you have to kill enough stuff for you to become Dr Jekyll again. The coins may be points, I'm not sure what the coins are when you are Hyde but really the most annoying part of the game is that they give you something that doesn't work. For example the cane that Dr Jekyll has can only kill a bee, wouldn't you rather have it get those other guys away??? I mean, the weapon is useless, that would be like playing golden eye for the n-64 and your gun doesn't work, what a tease.
