While this simulation with a quiz is very informative, and completely accurate, it doesn't do the word "game" much justice at all. It presents the information needed to complete simulations in textbook-like windows, doesn't randomize the questions or the answers to quizzes, and overall doesn't do anything to engage players into caring about the information being taught. It also has a couple glitches: the timer will count down before starting a simulation or not function at all, and the molecules sometimes won't go through the channels (both active and passive transport channels) due to sudden changes in going the opposite direction or appearing to bounce off the "rim" of the channel, which makes the levels somewhat frustrating. While it is a very good visual representation of cell membrane function, the creator now needs to focus more on ways to entertain and keep players involved in learning, and then perhaps expand this so that it teaches about other topics, maybe the functions of other cellular components, or maybe the movement of molecules within the cell (not just between the cell and the environment).
