I designed a banknote - the Infinibuck. I am making a bargaining minigame/ puzzle for the next game update and I don't, strictly speaking, need this banknote, but it seemed like a fun thing to draw. Like always this took way longer than it should have to make. 

And this is the person you will have to bargain with for some Infinibucks:

I will keep the specifics of how this puzzle will work for myself for now, but I will mention that the next update will have 5 new levels and 2 of those will be in a new category I want to heavily expand on. Same as I did with all the pattern recognition lessons, but with a different ruleset.
