Hmm I wasn't really sure what I was supposed to be doing. I tried a few times but wasn't able to get past 5 days. I liked the way the students came in at the start of the class though, that was quite funny. I think a bit of explaination would have helped here though.

Really neat idea. I think if you combined a lot of the information together into a single interface it might work better. Like if you could see students names attached to them, and then also see which desk was going to be cleaned on the same screen, I think it would help the concept of the game to be more clear
