Just enhance this code so that: - when total of several money pieces deposited in the incubator (bank) matches one of the money pieces values, the coins are transformed to a single sprite of that value (for instance, 2 coins of 1 euro should result in a single coin of 2 euro) - when a money piece is deposited in the splitter (market), the single money piece becomes splitted in 2 or more money pieces whose's sum is the same than the original money piece
