1. It is not very clear that the first screen is where you buy coupons.
2. It is even more unclear where you suppose to stick coupons. It just got to me on the 5th try, that they're go into that box "add coupons here", and not to the white sheet, which is the most intuitive place.
3. And it is unclear what's going on when you press "Play" Button, and why your coupons won't expire after 1 transaction.
Idea and art are great, but tutorial for dumb morons like me is not=) Tutorial needs to be more thorough and show not just where you pile up your coupons, but where you stick them, and what is going on after transaction is done, and also a buy screen.
