From the description I thought that this was a role-playing game, but I was wrong; it's a puzzle game. I would call the video (on the product page) very misleading.
That said, it's not a bad game, just nothing special. You are a nurse and have to direct patients as they enter the hospital, then send them to the correct department and (where applicable) take them their medicine from the pharmacy. You can buy new machines and other 'furniture', and then sell them again, but that's about it. In each new level, there are new machines etc available to buy.
Within its limitations it is fun, but if you don't like puzzle games I suspect you won't like this at all.
I found a bug that happens on levels with an elevator - that sometimes it 'sticks' and the nurse just won't go to the desired floor. Clicking repeatedly from nurse to elevator floor to patient and back (several times) eventually clears the problem, but it's not ideal, and is something that should have been picked up in testing.
