I did try that idea but I found it to be too frustrating because the machine would never give me the drink I wanted. With only 3 slots it meant that you were spending money pouring lots of drinks that you had to throw away. I totally agree with you and wanted to add more complexity but I ran out of time but didn't want to be frustrate for the player. I really appreciate the honest feedback and yes this was my first submission ever and it was really hard hahaha. Thank you kyboon!
