I'm a medical student, now this game isn't very usefull anymore but for new students that still need to learn everything i think it's great (for the students who still need to learn to study more and play less).
I don't think people should get more time, because it should be knowledge that is basic stuff without thinking.
If you make more of this games with the functions or nerve and arteries would be great. I rate this game 5/5. It's the first i find related to medical studies (when i was younger i searched long time for this kind of educational games and never found anything)
