cool idea, terrible design, too low budget... at $0 you can't do anything, so there could be at least game over.
problems:
adding ingredients is not as intuitive, so before game even started, I made mess, than I figured how to put items into the cauldron but after I finished potion, customer was gone, I though he was happy and left but no, the potion was still there, so for next customer I made more mess, than realised I have to finish potion, than few more misstakes and here we go, $0... game needs something like tutorial section or bigger budger, because 3 ingredients + $10 for 2 more is not enough to try, fail repeat
