cool minigame, very good use of the theme and limitations.
won the first game easily, but in the second one either i didn't understand what i was asked to buy, or they required 2 horns, but there was only 1 on the shelves.(
The items on the list are (supposedly) guaranteed to spawn, did you try using up and down or w and s for moving on the shelves? Even on the lowest difficulty there are 4 shelves.
