HOMEWORK SALESMAN SECRETS?

I just wanted to know if anyone knows of any secrets or such for Homework Salesman. I googled for it but there is very little documentation anywhere.... I don't care for easter egg spoilers, but if there are any legit secrets or tricks I can use it would be great if someone could tell me.

It would probably be more effective to ask this on the Homework Salesman game page itself.

Thank you for the advice :P
