Yes but the ingredients need to be dragged on the shelf after being right clicked, right ? That involves mouse coordinates ! The game gives of papa's taco mia vibes, its great. But yeah this mechanic wasn't allowed I believe.
Actually it's not dragging, you just need to click once, then the item attaches itself to mouse, when you click again it deattaches, i'm asking the jam owner now :') but as i recall clicking and dragging was counting as one input, i'm not sure tho, i'll comment when i guarrentee the input thingy
