I keep messing up and adding wrong ingredients, i think there should be a restart button (because you wouldnt be able to 'go back' making coffee, but you can always dump it out and remake it !!!
Thanks for your comment! I went out of token so couldn't find the space in my cartridge to add a restart button (that's how pico-8 works). But you have a built-in reset function : press return and select reset cart ;)
