yeah that'd probably have been a better way of doing it, wish i'd thought of that before the jam ended but oh well.
it's unfortunate because remembering the orders was never supposed to be a big part of the game's challenge, if i were to make a full version i'd have it so you'd need to manually enter what the customer's order is on the register screen while they're ordering so you'll have a reference to remember everything but you'll still need to pay attention to what's being said.
