I like it. A lot of upgrades, a lot to do. However, when you replay levels it gives you the same students with the same requests. Try randomizing it. Also make more levels that get even harder. Also, when my main teacher was not tied down and i was sending a student up the elevator, for some reason she went with him. I understand the logic behind it, being that the player might use her there but it got annoying when all i wanted to do was send the student and she went with him. Too often i had another student who needed her downstairs, i had to go back up and tell her to go down etc etc. when i didn't want her going up at all. Try making it so that when i put the student in the elevator, he goes alone and if i want her to go to all i need to do is click on the elevator again. Question: why does it have 10 levels showing but at level 7 it tells me game over?
