The arrow keys also control the camera, so I have to clue what I'm depositing. No rating for now.
Some feedback would be nice
A little more info:
You select the banker and choose ''Deposit''. A green number shows above your head. When you then press left arrow the number will get larger and larger untill you release it. With rigth arrow the number will smaller and smaller. So, when pressing down arrow you cancel the whole operation. pressing up arrow will complete the operation, that is if you have enough money in or outside of your bank-account. If it's too large you need to reduce the number.
