Here is what Id change

Great game! Cant believe its this good out of the box.
- Add a flip switch that turns all the bills into the "negative" version of themselves so if the ATM goes $1 over they can reverse and put $1 back in the register.

- Make sure the puzzles can always be solved. Sometimes needed bills are crossed out.

- Add a kids mode with a two options 1) a slower timer 2) no timer.
