I didn't enjoy this game, because it was just far too bland. I appreciate you trying to make an educational game. It just doesn't work here because it's just a bunch of images over and over. I didn't even feel like I learned that much. Maybe if you made it more about the kinds of classes I'm studying in college right now, I would like that. I don't know why the robots are there.
It seems like something with a quiz wouldn't have things like that. I don't even know how many times I have to click back in order to go to back to where I came from. You should do this in an entirely different format. Make the text more interesting. There isn't much unique here.
