This is insane! Extremely impressive that it was made in Desmos, but beyond that there is obviously thought put into the design. The first thing I noticed that I really liked was that the player's hurtbox is at Mabels FEET where they belong in a game like this, where you walk on the ground. A lot of people don't think about this, at least not in other similar jam titles I've seen.
The second thing I really like is that the game shows you how many of an item you can buy at any given point. Truly using Desmos to it's full potential. Great job!
