Cool game! I feel like just making the shakes is really fun. I don't know exactly what I'm making but I think might be the point. I also don't really get how this fits the theme.
Thanks! The idea was that you don't know what you're giving them at first, so you have to find out what ingredients you should use with trial and error, and the customers will usually be unhappy with what you try out, which is the failure, but then you learn what to give them, progress :d
