Great game so far, thanks for your hard work on it! As noted I found the long lists at either side of the screen a little disconcerting. Perhaps as the ingredient/potion list is a reversed binary tree (2 items always become 1 when moving to the next tier) a fixed tree-like layout on the playing field could eliminate the need for the two bulky lists altogether by giving each item it's own buy and sell button on the field?
